Utilising Parker's range of patented proprietary technologies, there are 1,000's of systems installed worldwide. These technologies offersome unique performance benefits, including guaranteed ultra high purity gas, silent operation, minimal moving...

common sight in many laboratories: a default for supplying analytical instruments with their gas requirements, high-pressure gas cylinders are familiar and provide the gas that's required, so it could be said that the old adage, 'if it isn't broke, don't fix it,' could well apply. Despite this, increasing numbers of analytical instrument users are choosing to supply their GC FID, LC/MS and other types of instrument with gas via an analytical gas generator. Driving this decision will be a combination of factors broadly grouped into four areas; safety, cost, convenience and purity. Safety...

re-calibration, are required before samples can be run. Life is more convenient with a gas generator as there's no unplanned downtime. Analytical gas generators only require simple quick maintenance which can be planned for - they don't unexpectedly run-out of gas halfway through analysis. Increased Purity... Analytical gas generators provide a constant source of gas. This removes the variations in purity between cylinders, helping to improve sensitive analyses. Purity is also preserved because there is no chance for impurities to enter the gas pipes, which may happen as cylinders are...

ENGINEERING YOUR SUCCESS. The Analysis of 16 EPA PAHs by GC/MS using Mark Wilkinson (mark.wilkinson@parker.com), James Heseltine (james.heseltine@parker.com) The aim of this technical paper is to optimize and produce a robust and repeatable method for the analysis of 16 EPA PAHs by GC/MS using generated hydrogen carrier gas, over helium. This yields vastly improved analytical performance with shortened run times, whilst eliminating laboratory hazards associated with high pressure vessel usage, storage and handling. Hydrogen is the choice of carrier gas for many applications, due to faster...

Detection limits of lppb were easily achieved, with excellent baseline resolution. 10 replicates were ran at this level, with typical RSD's of <0.1, and signal/noise (s/n) ratios varying between 5 and 20 (typically <10). Standards were prepared in Dichloromethane over a range of 5 to lOOppb. Calibration over this range showed excellent linearity with all compounds Late compound tailing - Helium Elimination of peak tailing ■ Typically, late eluting PAHs tend to tail, sometimes quite badly, making integration difficult, and peak asymmetry poor. In the above example, you can see clearly that...
