Direct Analysis ofGases Using a NewGas Sample IntroSystem and ICP-MSKouhei Nishiguchi, Keisuke UtaniSumitomo Seika Chemicals Co.
Introduction The direct introduction of gas samplesto an ICP-MS isn’t a widespreadapplication because of the difficultyof maintaining the plasma and locating suitable calibration standards. It is, however, a desirablemethod in terms of the potentialdata quality and speed of analysis.At Sumitomo Seika Chemicals, wehave developed a system capable oftransferring the particulate substances contained in a gas sampleinto argon using a gas exchanger. Inorder to eliminate any changes in thesample gas flow, we used a sampleintroduction system consisting ofan aspirator and a pressure equalizer.
Instrumentation
Figure 1. Schematic of Gas exchanger
The gas exchanger (Figure 1) isdesigned so that argon flows incountercurrent through the outerside of the porous tube. Sample gasthat is introduced into the centraltube is dispersed, passes throughthe porous wall and is eliminatedon the outer side. The argon sweepgas passes across the porous wall inthe opposite direction and mixeswith any particulates within thecentral tube. Particulates and argonpass along the tube to the outletand into the plasma. The aspiratorand the pressure equalizer smoothany changes in sample gas flowrates due to the pressure differentialbetween the inner and outer sidesof the tubes and/or due to the composition of the sample gas. Thishelps to maintain a constant flowrate of the sample gas.
The standard (reference) elementgas generator used in our experimentsis capable of supplying a standard gascontaining 2.6 µg/m3 of molybdenum

and 4.1 µg/m3 of tungsten at a flowrate of 50mL/min.
An Agilent 7500cs ICP-MS was usedduring this study. Because the particulates contained in the gassamples are extremely small, typically0.01 - 0.1µm, a high sensitivity ICP-MSlike the 7500cs is required. A diagramof the gas analysis system is shownin Figure 2.
Results and Discussion No drop in the reference gas (tungstenor molybdenum) sensitivity wasobserved even when the sample gas(N2, CO2, or 10% SO2) was introducedat flow rates of up to 500 mL/minthrough the gas exchanger. Figure 3shows the signal for the iron isotope(m/z = 56) obtained from introducingthe ambient air of the laboratory.The iron contained in the suspendedparticulates floating in the ambientair was measured in real-time.
This direct introduction method isextremely useful in achieving a higherdetection sensitivity than is possiblewith the indirect method of introducing a solvent into the ICP-MS.

Figure 3. Iron in ambient air
Direct introduction makes it possibleto introduce the total amount ofmicro-particles contained in thesample gas into the plasma. The signals of the elements contained inthe particulates are apparent in theform of spikes because of the extremely narrow peak widths.
ConclusionWith the use of the sample introductionsystem based on a gas-exchanger asdescribed here, it is possible toseparate particulates contained ingas samples, including air samples,and introduce the sample gas intothe plasma with argon. This opensup the possibility of using ICP-MSeffectively in a wide range of applications, including the monitoringof deleterious elements containedin sample gases such as ambient airand exhaust gases.
Investigations are now in progresswith regard to calibration methods,including the calibration of standardmetal element gases. We are confidentthat it will soon be possible to perform real-time monitoring ofgaseous samples using ICP-MS.

Success Story:Nestle Waters:Certification of 7500ceMethod for TraceElements in Water Dr. Eric Poitevin, X. LecozChemistry Laboratory, Vittel, [email protected]
Nestlé Waters manage a portfolio of75 brands, bottled at 103 productionsites. With sales accounting for almost10% of the Nestlé Group’s consolidatedsales, quality of product is top priority.All of Nestlé Waters’ bottled watersundergo the same strict quality controls and adhere to differentlocal and international regulations.
Nestlé’s worldwide center for waterscience is housed in the ProductTechnology Centre (PTC), basednear the Vittel and Contrex bottlingplants in France. Areas of expertiseinclude: • Bottled water• Water resources control• Bottling technology• Packaging technology• Industrial practices
The Central Laboratory, which formspart of the PTC, carries out over200,000 chemical and microbiologicalanalyses every year. It is equippedwith the latest instrumentation todetect, identify and qualify waterquality parameters, even at lowconcentrations.
All waters are also subject to tastetesting in the sensory evaluationroom. The panel of carefully selectedtasters establishes organolepticprofiles – subjective, sensory judgments based on the experienceof the evaluator – on finished products and new products.
Evaluation of ICP-MSIn 2003, the inorganic testing facilitywithin the Central Lab, was equippedwith ICP-OES for major elements(calcium, magnesium, sodium,potassium, sulfur and silicon) andGFAAS for trace elements analysisin bottled waters. With the largeworkload, operating two instrumentsin order to assay one sample for thedesired suite of elements was laborintensive. To relieve the strain on
Method Validation for MajorElements in WaterAlthough currently all major andminor isotopes are analyzed in thesame analytical run using the7500ce ICP-MS, external validationfor the major components (majorcations: calcium, magnesium, sodium,potassium and major anions: siliconexpressed as silica and sulfurexpressed as sulfates) will followlater in 2006.
Future ProjectsNow that the 7500ce ORS is takingcare of the day-to-day workload ofmineral analysis, we intend to applyit to research projects important toNestlé Waters including:• Monitoring of impurities of added
salts in waters e.g. bromine• Improvement of water processes
e.g. iodine• Low level analysis of mercury
ConclusionsInvestment in the 7500ce ORS ICP-MSallowed us to achieve our aim ofreplacing multiple techniques witha single instrument. The ORS iseasy to use and is highly effective atremoving interferences eliminatingthe need for interference correctionequations.
the lab, ICP-MS was evaluated, as areplacement technique for the existing technologies.
The Agilent 7500ce ICP-MS wasinstalled in the lab in 2004 and itwas soon apparent that the newinstrument could easily accommodatethe workload, with additionaladvantages:• Better limits of detection• More reliable results with
Octopole Reaction System (ORS)interference removal capability
• Faster throughput with ISIS and CETAC ASX-520 autosampler
• Spare capacity to analyze non-routine and urgent samples (newwells, new products, water treatment, and process improvement)
Quality Certification for ICP-MS7500ceThe chemistry department withinPTC was awarded COFRAC (FrenchCommittee of Accreditation)Certification in 2005 for its trace element analysis of drinking watersby ICP-MS. The COFRAC certificatesare equivalent to those issued byEuropean and international bodiese.g. ISO 17294-2:200 (Water Quality– Application of ICP-MS-Part 2:Determination of 62 elements), andprovide assurance about the qualityand reliability of analysis.
Fifty-six trace elements are now routinely and simultaneously monitored in the PTC chemistrylaboratory below 1 µg/L (ppb) inwaters coming from any of the 103production sites within the NestléWaters group. Samples can containtotal dissolved solid (TDS) contentup to 3 g/L.

Arsenic Speciationin Urine BecomesRoutineTetsushi Sakai and Steve Wilbur,Agilent Technologies
Arsenic exposure may lead to canceror other adverse effects, but thetoxicity is strongly dependent on thespecies. Of the five As species mostcommonly found in human urine,the order of toxicity is: As(III)(arsenite) > As(V) (arsenate) >DMA (dimethylarsinic acid) ≥ MMA (monomethyl arsonic acid) >> AB(arsenobetaine). While HPLC-ICP-MSis well accepted as the analyticaltechnique of choice for As speciationin urine, some remaining difficulties have prevented the technique from becoming routine.These are:
• Finding chromatographic conditionsthat will separate the 5 most important species as well as inorganic chloride in a reasonabletime, with good retention time reproducibility, dynamic range and sensitivity.
• Resolving or eliminating the ArClinterference on As which is derivedfrom the high NaCl concentrationin urine samples
• Avoiding clogging of the ICP-MS interface from total dissolved solids (TDS) contained in the urine and HPLC buffers.
Optimized Conditions
An Agilent 1100 Series HPLCisocratic pump, with autosampler,thermostatted column compartment,and vacuum degasser was coupledto an Agilent 7500ce ICP-MS systemfitted with an Agilent MicroMistglass concentric nebulizer. TypicalICP-MS conditions were used for Asanalysis, including; forward power:1550 W, sample flow rate: 1 mL/min,total carrier gas flow: 1.12 L/min.As was monitored at its elementalmass: m/z = 75.
Column SelectionA new column was developed andmanufactured by Agilent.Column G3288-80000

Mobile PhaseThe basic mobile phase consisted of:• 2 mM phosphate buffer solution
long term stability and robustnessof the method (Figure 1B).
ConclusionsA new HPLC-ICP-MS method capableof separating all 5 important arseniccompounds in human urine within12 minutes has been developedthrough careful, systematic optimization of all parameters,including the development andmanufacture of a new column. Themethod is robust enough for theanalysis of undiluted urine withlimits of detection of 0.1 µg/L orless for the individual As species.

Interference RemovalThe new Agilent G3288-80000column provides the necessarychromatographic resolution to completely separate inorganic chloridefrom the arsenic species underisocratic conditions, thereby eliminatingthe ArCl interference on As.
As a result, this method is suitablefor use with the non-ORS 7500aICP-MS as well.
Analysis of Urine SamplesThe new methodology was appliedto the analysis of NIES CRM No.18urine, using a 5 µL injection of theundiluted sample (Figure 1A). Theresults agree well with the certifiedvalues (AB 66.0 µg/L, DMA 31.0µg/L). Repeated injections (n = 15)of a 1/10 diluted human urine samplespiked at 5 µg/L demonstrates good

New Inert kit andPFA nebulizerTomo Yamada, Agilent Technologies Inc., Japan
After extensive development andtesting, Agilent has introduced anew inert sample introduction kitand a new design PFA concentricnebulizer for the 7500 Series.
New Agilent Inert Kit
The new inert kit (G3285A) is all-PFA and features an o-ring free endcap, push-fit torch connector anddemountable torch. The inert kit hasbeen carefully designed to fit perfectlyon the 7500 Series mainframes. Anexhaustive testing and design programhas resulted in excellent long termstability and elimination of dropletformation in the connecting tube –the weak point of any inert sampleintroduction system. Both platinumand sapphire injectors are availablewith different internal diameters(i.d.) to suit every application(Table 1). An optional 2nd gas portat the torch connector allows forthe addition of oxygen for organicsolvent analysis. The new inert kit(#101 with sapphire injector) willbe included as part of the accessorykit shipped as standard with theAgilent 7500cs from September.
New PFA Concentric Nebulizer
In addition to this new inert kit, acompletely new-design PFA concentricnebulizer has also been introduced. It produces a highly reliable andreproducible aerosol and can beused with the inert kit and also the
significant operator intervention inachieving and verifying optimum CRCperformance. While Agilent ICP-MSsystems are simple to tune and operate in CRC mode, we supportEPA’s contention that this needs tobe validated. We believe that a performance-based approach usinginterference check standards similarto those required by EPA-6020 willmeet the requirements, and wehave provided data and guidance tosupport this.
Furthermore, Agilent is supportingthe efforts of the American Council ofIndependent Laboratories (ACIL) towork with the National EnvironmentalLaboratory Accreditation Council(NELAC) and EPA to validate theuse of collision cell technology forall applications of Method 200.8.
In the meantime, please be awarethat, as issued, this memo applies onlyto drinking waters for regulatorycompliance, and not to any otheruses for method 200.8. Since mostdrinking waters are relatively freeof complex matrix, the impact ondata quality will be smaller than forother matrices.
The upside is that, through thismemo, the EPA Office of Water hasfinally, formally declared their intentto develop a modified method fordrinking water compliance monitoringusing CRC technology.
In SummaryAgilent Technologies still recom-mends the 7500ce for environmentalapplications at this time. We fullyexpect the EPA to approve the use ofCRC-ICP-MS for drinking waters andother applications in due course.
Please feel free to contact me directlywith questions or [email protected]
for the Agilent integrated auto-sampler (I-AS) is also available. Allnew inert kit and nebulizer optionsare available on the Agilent pricelist from August 1st, 2006.
Use of Collision Cellsfor EPA Method 200.8for Drinking WaterSteve Wilbur, Agilent Technologies Inc., USA
As a leading manufacturer of collision/reaction cell (CRC) ICP-MSsystems used in the environmentaltesting industry, we would like to helpclarify the intent and ramificationsof the recent EPA Office of Watermemo (July 14, 2006) stating thatthe use of enabled CRC technologyis currently not permissible fordrinking water compliance monitoring using EPA method200.8.
This memo is the result of the rapidincrease in the use of CRC-ICP-MS inrecent years without the correspondingdevelopment of appropriate qualityassurance protocols to insure thatthe data generated is equivalent to, orbetter than, that using mathematicalinterference correction equations.
Since the approach to CRC technologyvaries significantly with the variousICP-MS manufacturers, devising asimple, universal set of QA/QC protocols is challenging. However,Agilent had been actively supportingEPA’s efforts to validate a collisioncell enabled version of method200.8 with appropriate quality assurance criteria to insure equivalentor better results when compared withmathematical correction equations.
Technology Not in QuestionEPA, in general, supports the use ofCRC-ICP-MS and calls it a major technological advance. Their mainconcern is in minimizing what they perceive as a requirement for
