ABSTRACT BODY:  Abstract: The photoinization detector (PID) has been shown to be one of the most sensitive gas chromatography (GC) detectors for measuring VOC’s and selected inorganic compounds (H2S, NH3, PH3…). We have combined the PID with a field portable GC analyzer and a battery operated concentrator that will enable low ppt of VOC’s to be detected with a 1-2 minute sampling time. The photoionization detector (PID) has been redesigned to reduce the dead volume to 50 µL and improve the sensitivity to by 5-10 fold. The detection limit for benzene has been reduced to < 500 ppt without the concentrator. The redesigned PID can operate with a sealed discharged lamp (10.6 eV) and we have added a glow discharge lamp with higher energy (11.6 & 11.8 eV) using argon. This will allow the detection of alkanes down to ethane, chloroalkanes and chemical agents. It is also one of the most sensitive detectors for formaldehyde. Potential applications include atmospheric monitoring, fenceline monitoring of hazardous air pollutants (HAPs), indoor air pollutants, ppt levels of toxic gases including chemical agents.
