GC Detectors Thursday, July 7, 2011 Measurement of ppb Levels of Gasoline in Groundwater by Portable GC-PID Contamination of groundwater and soils by leaking underground storage tanks continues to be a serious environmental problem. Twelve years ago, the EPA was monitoring about 370, 000 leaking underground storage tank sites in the United States. Only about 5% were scheduled for site cleanups in 2001. Cleanups are funded by the EPA's LUST Trust Fund, which was funded at a level of

Gas Analysis
Gas Analysis Thursday, July 7, 2011 New Features of the Model 301MP Area & Stack Monitor We used a photoionization detector (PID) to analyze ppb levels of ethylene oxide (ETO). The range of the Model 301MP Area Monitor was extended so that the same analyzer can be used to measure both workplace exposure levels of ETO and stack levels. This 25 point sequencer has separate banks for the permissible exposure (PEL) and stack levels. The software was modified and a programmable sample ahead feature
