Useful Terminology BTEX is an acronym that stands for benzene, toluene, ethylbenzene,

and xylenes.These compounds are some of the volatile organic compounds (VOCs) found in petroleum derivatives such as petrol (gasoline). 

Toluene, ethylbenzene, and xylenes have harmful effects on the central nervous system. BTEX compounds are notorious due To the contamination of soil  and 

groundwater with these compounds. Contamination typically occurs near petroleum and natural gas production sites, petrol stations, and other areas with storage tanks containing gasoline or other petroleum-related products.

The amount of 'Total BTEX', the sum of the concentrations of each of the constituents of BTEX, is sometimes used to aid in assessing the relative risk or seriousness at contaminated locations and the need of remediation of such sites. Naphthalene may also be included in Total BTEX analysis yielding results referred to as BTEXN. In the same way, styrene is sometimes added, making it BTEXS.

Useful Terminology Flame Ionization Detector FID

The operation of the FID is based on the detection of ions formed during combustion of organic compounds in a hydrogen flame.

The generation of these ions is proportional to the concentration of organic species in the sample gas stream. In order to detect these ions, two electrodes are used to provide a potential difference

Gas Chromatograph (GC) GC is a chemical analysis instrument for separating chemicals in a

complex sample. It uses a flow-through narrow tube known as the column, through which different chemical constituents of a sample pass in a gas stream at different rates depending on their various chemical and physical properties and their interaction with a specific column filling, called the stationary phase. As the chemicals exit the end of the column, they are detected and identified electronically. The function of the stationary phase in the column is to separate different components, causing each one to exit the column at a different time

VOC Analyzer – Model 4060 GC

Model 4060 is a microprocessor based instrument ideal for the specific monitoring of trace levels of Benzene in gases such as carbon dioxide, air, and nitrogen. Designed as an on-line analyzer the Model 4060 comes with three standard ranges, the most sensitive at 100 ppb full-scale. This analyzer can be configured to measure BTEX measurements + 1,3 Butadiene.

Because of its relatively high sensitivity to most organic compounds, the flame ionization detector is a powerful tool for measuring hydrocarbon impurities in other gases. It also provides a linear response over a wide range of analysis . The Organic compounds from the sample stream or separation column are injected into the detector housing where they are mixed with Hydrogen and air before entering the detector jet where the mixture is burned. During this process, organic compounds are broken down into carbon fragments and acquire a positive charge (i.e., become ionized) at the surface of the anode. Carbon fragments are detected by the collector. The signal is then amplified and sent to the data processing system

Model 4060 GC Modes of Operation: The analyzer has 2 modes of operation depending on the position

of the GC Sampling Valve.

Sampling Mode (Valve Position A)

the analyzer configures the operational valve to back flush the column and charge

the sample loop. The Sample Mode is programmed to continue for a 7 minute

period by factory default; however, it is usually modified to match the needs of a

particular process. It is possible to set the Sample Mode duration up to 25 minutes.

Analysis Mode (Valve Position B)

In this mode the analyzer configures the sampling valve to feed the gas in the sample loop

through the column and to the detector. The eluted sample from the column is fed to the FID

for the analysis of the compound of interest in the hydrocarbon stream. If configured to do

so, the analyzer may read the detector for a programmed 5 second period at some point

within this mode cycle to obtain a baseline reading for further calculation. This mode is

usually programmed to continue until the compound of interest is fully eluted from the column. It is

possible to set it up to 25 minutes.

4060 GC - Specification

11

4060 GC - EquipmentThe following supporting gases and hardware will be required to operate the

analyzer:

1. Fuel: A cylinder containing a hydrogen gas, zero gas quality composition will be required to supply the fuel for the flame ionization burner. The cylinder is to be equipped with an oil-free metallic diaphragm regulator (dual stage).

2. Blanket Air: A cylinder of compressed air, zero gas quality will be required to maintain the proper atmosphere within the cell. The cylinder is to be equipped with an oil-free, dual stage, metallic diaphragm regulator.

3. Carrier Gas: A cylinder of nitrogen gas, zero gas quality, equipped with dual stage metallic diaphragm regulator is required.

4. Span Gas: A cylinder or a permeation device system, capable of generating known concentration of benzene and/or other aromatic hydrocarbons of interest, will be required to calibrate the analyzer.

5. Sample Pressure Regulation: An oil-free, metallic diaphragm regulator must be installed at the sample point when possible.

4060 GC - Tracs Diagnostic Software Tracs™ software developed by TAI is a unique program to unveil

chromatogram and compound retention sequences on which concentrations of compounds of interest are calculated. It provides valuable access for an ordinary user to look into inside the complicated GC world with a computerized tool. It suits the needs for high accuracy in GC technique and for ease of communication in digital format.

VOC Analyzer – Model 4060 GCALARM RELAYS:

The nine alarm-circuit connector pins connect to the internal alarm relay contacts. Each set

of three pins provides one set of relay contacts.

Threshold Alarm 1: Can be configured as high (when concentration is above threshold), or low

(when concentration is below threshold).

Can be configured as failsafe or non-failsafe

Can be configured as non-latching

Can be configured out (defeated).

17

VOC Analyzer – Model 4060 GCThreshold Alarm 2: Can be configured as high or low

Can be configured as failsafe or non-failsafe

Can be configured as non-latching

Can be configured out (defeated).

System Alarm:

Actuates when DC power supplied to circuits is unacceptable in one or more

parameters. Permanently configured as failsafe and latching. Cannot be defeated

18

VOC Analyzer – Model 4060 GCThe Alarms Function:

The Model 4060 is equipped with two alarms and a system failure alarm relay

1-DEFEATED: If an alarm is defeated, its relay is de-energized, regardless of failsafe condition. A defeated alarm does not react to a transition over its trip point in either direction.

2-HIGH: If an alarm is set as HIGH, it will not create a new alarm condition if the analysis concentration is below the trip point, if the analysis concentration is above the trip point, then an alarm condition will be created or maintained.

3-FAILSAFE: A non-defeated alarm that is in FAILSAFE mode energizes an alarm relay in a non-alarm condition and de-energizes an alarm relay in an alarm condition.

19

VOC Analyzer – Model 4060 GC 4-LATCHING: The latching property configures the alarm such that the user

must manually relieve the alarm condition even though the concentration no longer violates the trip point of the alarm. So, if an alarm is NON-LATCHING, and the analysis concentration temporarily drifts above the trip point of a HIGH alarm, the alarm condition occurs only during the time the concentration is above the trip point. If that alarm were LATCHING, the alarm condition would persist (even though the concentration is no longer above the trip point), until the user released it.

5-TRIGGER POINT: This is the threshold at which an active alarm can enter into alarm condition. If an alarm is HIGH, ACTIVE, and set at 20.00 ppb, then when the analysis concentration is at or above 20.00 ppb an alarm condition is initiated or maintained.

VOC Analyzer – Model 4060 GC ELECTRO-STATIC DISCHARGE

Modern electronic devices such as the types used in the various electronic assemblies of your analyzer, are very small, require very little power and operate very quickly. Unfortunately, the same characteristics that allow them to do these things also make them very susceptible to damage from the discharge of static electricity. Damage to components occurs when these static charges come into contact with an electronic device.

Temporary anti-ESD work area Always wear an Anti-ESD wrist strap when working on the electronic assemblies of

your analyzer.

Simply touching a grounded piece of metal is insufficient. While this may temporarily bleed off static

Always store sensitive components and assemblies in anti-ESD storage bags or bins
