HotBlock™ 200: Operation and Instruction Manual Installation, Safety & Maintenance

About Your Environmental Express HotBlock™ 200 Series

Environmental Express HotBlock 200 Series provides an efficient method of digesting and storing water, wastewater, soil and sludge samples for metals analysis. These innovative digestion systems allow samples to be digested in a corrosion-free environment using an external touch screen controller. Samples are handled in a small area with minimal radiant heat loss. Users should be aware of potential dangers from heating certain types of compounds. Such hazards may include explosion or the release of toxic or flammable gases.

Definitions/Markings

Each HotBlock™ 200 displays certain markings and symbols. All personnel working with the HotBlock™ 200 should have an understanding of the following symbols and definitions:

• V = voltage• ~ = alternating current• Hz = frequency• A = amperes

This symbol means Caution Hot Surface. The surface of the HotBlock™ may be too hot to safely touch with bare hands.

This symbol means Read and become familiar with instructions before operation of instrument.

Installation of your HotBlock™ 200:

1. Plug the controller into an appropriate outlet. The HotBlockTM 200 must be plugged into a 15 or 20 AMP receptacle. Thecontrollers can be mounted to the side of a metal hood using the included magnets. The black controller mountingplate can also be removed from the housing and installed in an empty electric receptacle on the fume hood.Ensure installation in a receptacle is done by a qualified electrician.

2. The cord running from the HotBlock™ plugs into the corresponding receptacle on the front of the controller. If usingtwo blocks, you must use SC1832 to have two receptacles. Attach the cord from the second block to theappropriate receptacle.

3. The HotBlock or blocks should be placed in a vented enclosure while the controller must remain outside theenclosure for ease of operation and to keep the controller removed from the corrosive digestion environment. (Seeinstallation requirements in the next section).

Failure to locate your HotBlock™ 200 controller outside the fume hood will void your product warranty.

Installation Requirements

Locate the HotBlock™ 200 under a fume hood with a minimum face velocity of 100fpm, and allow a minimum of 2" of space on all sides. The following environmental conditions should be observed:

• Ambient temperature range: 5-45°C• Ambient relative humidity: 0-100%RH• Altitude: sea level to 2500 meters

HotBlock 200 is rated as Pollution Degree 2 and Installation Category 2.

The HotBlock 200 Controller MUST be located outside the fume hood. Failure to do so will void your product warranty.




Electrical Requirements

• Required Voltage 120 volts, ~60Hz, Current - 9A per block (all HotBlock™ 200 systems are alsoavailable in 240V)

• Power should not vary greater than ±10%. Connecting to the power supply must be done with the supplied heat-resistantpower cord or equivalent.

• For safety reasons, a separate power receptacle should be provided for HotBlock™ 200 system. Do not use extension cordsor outlet adaptors. Make certain that power outlets are earth-grounded at the grounding pin.

Potential Hazards

The HotBlock™ 200 should only be operated by properly trained personnel using standard laboratory safety practices.

• Use extreme caution when operating the HotBlock™ 200 digestion blocks. Plastic and graphite surfaces of the blocks maybe too hot to safely touch with bare hands.

• The HotBlock™ 200 components contain electrical circuits and devices and compounds operating at dangerous voltages.Contact with these circuits, devices and components can cause serious injury or painful electric shock.

• Proper grounding is essential to avoid a potentially serious electric shock hazard. Ensure that there is an internal groundconnection between the metal base of the system and the 3-pin earth-grounded receptacle.

• For safety reasons a separate power outlet receptacle should be provided for each HotBlock ™ 200 system. Do not useextension cords or outlet adaptors. Make certain each power outlet is earth-grounded at the grounding pin.

• Power requirements for individual blocks may be found on our website.

• Application of the wrong supply voltage can create a fire hazard and a potentially serious shock hazard, and could seriouslydamage the HotBlock™ 200 system. See specifications for individual components.

• Users should be aware of potential dangers from heating certain types of compounds. Such dangers may include therelease of toxic or flammable gases or explosion.

Maintenance

• Any service inquiries should be directed to Environmental Express Inc. Technical Service Department.

• After each use, clean exterior surfaces with a damp sponge to remove acid residue.

• For acid spills, sponge with a diluted solution of sodium bicarbonate followed by distilled water. Acid that is spilleddirectly into the digestion wells should be neutralized and removed.

• Before using any cleaning or decontamination methods except those recommended, check with Environmental Expressto confirm the proposed method will not damage your HotBlock™ 200.

• Avoid excessive spills, as liquid allowed to overflow into the HotBlock™ 200 casing can seriously damage electroniccomponents.




HotBlockTM Temperature Settings:

The pre-set factory “set point” temperature of your HotBlockTM is 106°C. Factory tests have shown that this temperature is “sea level safe.” Liquids in uncovered polypropylene tubes should not boil at this setting. Please note that the set point of the block is not the same as the temperature of the liquids being digested. The block temperature should be optimized for the specific digestion. The temperature of liquid contents of the digestion cup will vary according to:

• The material being digested

• The number of samples being digested

• The air movement of the digestion area

• The addition of a watch glass or reflux cap

If watch glasses are being used, the control point temperature should be lowered approximately 10°C to avoid boiling.

Note The maximum sample temperature tolerance for our polypropylene digestion vessels is 130°C.

Remember that the temperature display (current block temperature) is not the temperature of the sample. Sample temperature will usually be 10-15° less than the display temperature.

Safe-Sample™ Temperature Protection:

Your HotBlockTM is protected from runaway temperatures by a fail-safe alarm system. In the unlikely event that the heating system fails to respond to the controller, the Safe-Sample™ system will automatically shut the system off and display a visible alarm.

This alarm sequence occurs if the actual temperature of the block reaches a temperature that is fifteen degrees higher than the set point temperature. If this should occur, the HotBlockTM will stop heating, preventing the loss of samples. The HotBlockTM must be turned off, then turned back on to reset the alarm.

HotBlock™ 200: Operation and Instruction Manual Parts & Supplies

Polypropylene Disposable Screw-cap Digestion Cups Eliminate Transfer Steps.

• Available in 15mL, 50mL and 100mL volumes

• Certified for low metals background

• Volume certified

• Lined caps ensure a leak-proof seal

• Accurate graduations eliminate the need for graduated cylinders and transfer steps

These carefully engineered digestion vessels provide premium performance in your HotBlock®, HotBlock™ 200. Cups are molded of clarified homopolymer polypropylene, providing a higher working temperature and greater chemical resistance than commonly used co-polymer polypropylene.

Accurate, molded-in graduations allow analysts to easily reproduce volumes to within 0.5%. Vessels serve as graduated cylinders, as well as storage containers. After digestion is complete, the sample can be brought to volume and capped for storage, eliminating time-consuming transfer steps. The result is a “one-cup” system that greatly reduces labor and costs associated with metals preparation.

Screw caps are available lined with polyethylene-faced foam liners for a leak-proof seal (green and white caps only) or as a plug style closure (natural caps only).

Each box of cups comes with a certification of volume accuracy, as well as a Metals Background Analysis Report.

HotBlock™ 200: Operation and Instruction Manual EPA Method 200.2, Revision 2.8

Adaptation for EPA Method 200.2, Revision 2.8 for use with the Environmental Express HotBlock® Digestion System Revised 12.13

1.0 Scope and Application 1.1 The following procedures have been written as an aid to EPA digestion

procedure 200.2 for use with the Environmental Express HotBlock. EPA Method 200.2 is for the determination of total recoverable analytes in groundwater, surface water, drinking water, wastewater and (with the exception of silica) in solid samples such as sediment, sludge and soil. Use EPA Method 200.2 for reference while following the sample preparation steps outlined below. A complete list of elements appropriate for analysis is included in EPA Method 200.2. Analysis can be performed by flame atomic absorption, GF/AA, ICP and ICP-MS.

2.0 Apparatus and Materials 2.1 HotBlock for Metals Digestions — Model Number SC100, SC150*, SC154,

SC181, SC182*, SC189, SC191, or SC192* 2.2 Polypropylene Digestion Vessels — Catalog # SC475 (50mL) or # SC490

(100mL) or # SC415 (15mL) 2.3 Ribbed Watch Glasses, Catalog # SC505 or Reflux Caps, Catalog # SC506

(for use with SC490 vials for HotBlock SC150, use Ribbed Watch Glasses, Catalog # SC610)

2.4 FilterMate — Catalog # SC0401 (or appropriate FilterMate® or FlipMate®) for sample filtration if necessary *Note: For all procedures, when using the block with the SC490 digestion vials with

a 100mL sample, double the volume of all reagents and acids added.

3.0 Procedure, Aqueous Sample Preparation 3.1 Mix sample thoroughly to achieve homogeneity. For each digestion

procedure, transfer a 50mL sample (or appropriate volume for your lab) into the SC475 polypropylene vessel. For best results, weigh the sample directly in the vessel on a tared balance.

3.2 Add 1mL (1:1) HNO3 and 0.5mL (1:1) HCl, then swirl. Heat the sample in the HotBlock at 95°C for 2.5 hours without boiling. Place a ribbed watch glass (SC505) on top of the digestion vessel. Note: When using a watch glass, adjust the control point temperature of the HotBlock so that a 50mL, 5% acid solution is heated to 85°C BEFORE placing the watch glass over the sample. Laboratory tests have proven that the addition of the ribbed watch glass will add approximately 10°C to the sample temperature, bringing the sample temperature up to 95°C.

3.3 Using the polycarbonate transfer racks, remove samples from the HotBlock and allow them to cool.

3.4 After cooling, dilute samples to 50mL with DI Water. 3.5 If necessary, filter with SC0401 (or appropriate FilterMate® or FlipMate®)

to remove insoluble material. Note: The filtration step should be performed slowly with little pressure placed on the plunger. If excessive back pressure occurs, stop filtration and allow sediments to “settle out”. Applying pressure to the plunger may cause sample “blow through” allowing sediment to pass through the filter into the digestate.




4.0 Procedure, Solids Sample Preparation 4.1 Sieve a dried sample using a 5-mesh polypropylene sieve and grind in a

mortar and pestle. Weigh a representative sample of 0.5 ±0.01g into a digestion vessel.

4.2 Add 2mL of (1+1) HNO3 and 5mL of (1+4) HCl. Cover with a ribbed watch glass (SC505) or reflux cap (SC506) and place in the HotBlock at 95°C.

4.3 Heat sample for 30 minutes. 4.4 (Optional) Although step 3 is the final heating step for EPA Method 200.2,

if the sample is suspected of having a high concentration of organic compounds, it is recommended to complete this step: Add 2mL of 30% H2O2 to the well-cooled sample. Allow the exothermic reaction to occur (approximately 10 minutes) and place the sample back in the HotBlock at a temperature of 10° less than the original set point for an additional 30 minutes. The reaction with the H2O2 raises the sample temperature. Boiling should not occur if the temperature of the HotBlock is lowered. Note: H2O2 helps aid in the breakdown of high organic compounds in the sample thus creating a more complete digestion.

4.5 Using the polycarbonate transfer racks, remove samples from the HotBlock and allow them to cool completely.

4.6 Bring sample volume to 50mL with DI water. 4.7 If necessary, filter with SC0401 (or appropriate FilterMate® or FlipMate®)

to remove insoluble material. Note: The filtration step should be performed slowly with little pressure placed on the plunger. If excessive back pressure occurs, stop filtration and allow sediments to “settle out”. Applying pressure to the plunger may cause sample “blow through” allowing sediment to pass through the filter into the digestate.

All QC samples, concentration limitations, elemental lists and reagent specifications are addressed in depth in EPA Method 200.2. Safety concerns are also part of the full method. Follow the instructions listed in EPA Method 200.2. These steps should only be used as a guide to help improve the performance of your HotBlock.




Adaptation for EPA Method 200.7, Revision 4.4 for use with the Environmental Express HotBlock Digestion System Revised 12.13


procedure 200.7 for use with the Environmental Express HotBlock. EPA Method 200.7 is for the determination of total recoverable analytes in groundwater, surface water, drinking water, wastewater, and (with the exception of silica) in solid samples such as sediment, sludge and soil. Use EPA Method 200.7 for reference while following the sample preparation steps outlined below. A complete list of elements appropriate for analysis is included in EPA Method 200.7. Analysis can be performed by ICP.



(100mL) or # SC415 (15mL) 2.3 Ribbed Watch Glasses, Catalog # SC505 or Reflux Caps, Catalog # SC506




3.0 Procedure, Total Recoverable Elements, Aqueous Sample (EPA Method 200.7, Paragraph 11.2) 3.1 Mix sample thoroughly to achieve homogeneity. For each digestion

procedure, transfer a 50mL sample (or appropriate volume for your lab) into the SC475 polypropylene vessel. For best results, weigh the sample directly in the vessel on a tared balance.

3.2 Add 1mL 1:1 HNO3 and 0.5mL 1:1 HCl and swirl. Heat in the HotBlock at a sample temperature of 85°C and evaporate to about 10mL taking care that the cup does not go dry. This will take approximately 2 hours.

3.3 Cover the vessel with a disposable watch glass (catalog # SC505) and reflux an additional 30 minutes. Note: When using a watch glass, adjust the set point temperature of the HotBlock so that a 50mL, 5% acid solution is heated to 85°C BEFORE placing the watch glass over the sample. Laboratory tests have proven that the addition of the ribbed watch glass will add approximately 10°C to the sample temperature, bringing the sample temperature up to 95°C.

3.4 Using the polycarbonate transfer racks, remove samples from the HotBlock and allow them to cool. Bring samples up to volume with DI water.




3.5 If necessary, filter with SC0401 (or appropriate FilterMate® or FlipMate®) to remove insoluble material. Note: The filtration step should be performed slowly with little pressure placed on the plunger. If excessive back pressure occurs stop filtration and allow sediments to “settle out”. Applying pressure to the plunger may cause sample “blow through” allowing sediment to pass through the filter into the digestate.

4.0 Procedure, Total Recoverable Elements, Solids Sample (EPA Method 200.7, Paragraph 11.3) 4.1 For each digestion procedure, transfer 0.5g ± 0.01g of a dried sieved

sample into the SC475 polypropylene vessel. 4.2 Add 2.0mL (1:1) HNO3 and 5mL (1:4) HCl and swirl. Cover the vessel with

a disposable watch glass (catalog # SC505) and reflux an additional 30 minutes at a sample temperature of 85°C. Note: When using a watch glass, adjust the set point temperature of the HotBlock so that a 50mL, 5% acid solution is heated to 85°C BEFORE placing the watch glass over the sample. Laboratory tests have proven that the addition of the ribbed watch glass will add approximately 10°C to the sample temperature, bringing the sample temperature up to 95°C.

4.3 Allow to cool and bring to 50mL volume with DI water. 4.4 Filter with SC0401 (or appropriate FilterMate® or FlipMate®) to remove

insoluble material.

4.4 Place a ribbed watch glass (SC505) over the digestion vessel to reduce additional evaporation. Note: When using a watch glass, adjust the set point temperature of the HotBlock so that a 50mL, 5% acid solution is heated to 85°C BEFORE placing the watch glass over the sample. Laboratory tests have proven that the addition of the ribbed watch glass will add approximately 10°C to the sample temperature, bringing the sample temperature up to 95°C.

4.5 Gently reflux the sample for 30 minutes. 4.6 Using the polycarbonate transfer racks, remove samples from the HotBlock

and allow them to cool. 4.7 Add reagent water to bring the sample to the 50mL mark on the digestion

vessel. Cap and mix. 4.8 If necessary, filter with SC0401 (or appropriate FilterMate® or FlipMate®)

to remove insoluble material. Note: The filtration step should be performed slowly with little pressure placed on the plunger. If excessive back pressure occurs, stop filtration and allow sediments to “settle out.” Applying pressure to the plunger may cause sample “blow through” allowing sediment to pass through the filter into the digestate.

4.9 Prior to analysis, adjust the chloride concentration by pipetting 20mL of the prepared solution into another SC475 digestion vessel and bring up to 50mL volume with reagent water. If the dissolved solids in this solution are >0.2%, additional dilution may be necessary to prevent clogging of the extraction and/or skimmer cones. Note the dilution factor for concentration calculations. If the direct addition procedure is being used, add internal standards, cap and mix.

5.0 Procedure, Solid Sample Preparation 5.1 For each digestion procedure, transfer 0.5g ± 0.01g of a dried sieved

sample into the SC475 polypropylene vessel. 5.2 Add 2.0mL (1:1) HNO3 and 5mL (1:4) HCl and swirl. Cover the vessel with

a disposable watch glass (catalog # SC505) and reflux an additional 30 minutes at a sample temperature of 85°C. Note: When using a watch glass, adjust the set point temperature of the HotBlock so that a 50mL, 5% acid solution is heated to 85°C BEFORE placing the watch glass over the sample. Laboratory tests have proven that the addition of the ribbed watch glass will add approximately 10°C to the sample temperature, bringing the sample temperature up to 95°C.

5.3 Allow to cool and bring to 50mL volume with DI water. 5.4 Filter with SC0401 (or appropriate FilterMate) to remove insoluble material.

3.0 Reagents 3.1 Concentrated Reagent-grade HNO3 (5mL repipet dispenser recommended) 3.2 Concentrated Reagent-grade HCl (5mL repipet dispenser recommended)

4.0 Procedure 4.1 Transfer the wipe to the SC475 digestion cup. It is recommended that the

wipe is sent to the sampling area with a cup and wipe so no transfer steps are required. The wipe must be transported in a rigid-walled container according to the sampling procedure ASTM E1728.

4.2 Add 10mL DI Water, 2mL HNO3 and 2mL HCl. Cover with a ribbed watch glass.

4.3 Heat the sample for 45 minutes at 95°C. Note: When using a watch glass, adjust the set point temperature of the HotBlock so that a 50mL solution is heated to 85°C BEFORE placing the watch glass over the sample. Laboratory tests have proven that the addition of the ribbed watch glass will add approximately 10°C to the sample temperature, bringing the sample temperature up to 95°C.

4.4 Using the polycarbonate transfer racks, remove samples from the HotBlock and allow them to cool for approximately 10 minutes. Bring the sample to 50mL volume. If excess amounts of undigested material remain, filter the sample using a 2.0µm PTFE FilterMate®.

4.5 Cap and mix well.

According to AIHA Policies 2001- Revision Nov. 2000, one LCS, one matrix spike and one duplicate must be run every 20 samples. “The LCS shall be a solid matrix material with an established concentration obtained from a source independent of the instrument calibration and traceable to NIST or other similar reference material. Liquid spikes may not be used for preparing LCSs”.

Environmental Express does offer NIST-traceable spiked GhostWipe wipes (Catalog # SC4252). The range is 175 to 200µg of Lead per wipe.
