6. electrodes 4 5 is located in the ionization volume near the lamp window The polarizing electrode 4 is connected to the High Voltage DC source 7 the signal electrode 5 is attached to the amplifier 6 input The electric field created by these two electrodes forces both electrons and ions to drift towards their respective electrode creating a small current This current is amplified by the amplifier chip and the output analog signal is recorded and or displayed in digital or analog format The output signal is proportional to the concentration of ionizable molecules in detector s chamber and thus serves as a measure of concentration Major air components N2 O2 and CO2 have ionization potentials greater than the UV lamp and therefore are not detected For this reason PID is very useful for detection of a wide range of VOC s Volatile Organic Compounds in ambient air down to the low ppb concentrations without interference from air components The gaseous sample is delivered to the detector chamber a diffusion process Appendix I Ionization Potentials VOC TRAQ User s Manual Ionization Potentials Chemical Name IP eV Benzene 9 25 Benzenethiol 8 33 A Benzonitrile 9 71 2 Amino pyridine 8 Benzotrifluoride 9 68 Acetaldehyde 10 21 Biphenyl 8 27 Acetamide 9 77 Boron oxide 13 5 Acetic acid 10 69 Boron trifluoride 15 56 Acetic anhydride 10 Bromine 10 54 Acetone 9 69 Bromobenzene 8 98 Acetonitrile 12 2 Bromochloromethane 10 77
