| Alternative Gases for VOC Analysis | October 2013 |
Helium is becoming more and more difficult to find and store
Helium prices have increase and shortages have been reported Helium is the preferred carrier gas for Gas Chromatography/Mass Spectroscopy analysis and purges gas for purge and trap autosampler Demand for alternative gases to be used in Volatile Organic Compounds (VOCs) analysis Teledyne Tekmar will discuss employing hydrogen GC carrier gas and nitrogen purge gas to perform EPA method 8260 and 524 A working linear calibration curve, Method Detection Limits (MDLs), and a BFB tuning evaluation will be presented to determine the validity of alternative helium gases for VOC analysis
