PID Analyzers - Model 103+ -Photoionization (PID) Analyzer for VOC’s (PPM & PPB)

VOC’s ppm, benzene, 1,3 BD, ETO, TCE, PCE, VCM, THC, H₂S, NH₃, 1,3 BD, Hg, others: hundreds of VOC`s.

Hydroarbons, VOCs, LEL (IR), IR {CH4, CO2, N2O,} CO2, H2S, ETO, NH3, PH3, AsH3, benzene, TCE, PCE, 1,3 butadiene, TCA, Formaldehyde

Model 103 - PID -Analyzer for Total VOCs & Hydrides in Air & Water
HNU Systems, Inc. introduced the first commercial photoionization based instrumentation in 1974. In 2003, the company name and incorporation was changed as we became PID Analyzers, LLC. Nearly 50,000 of the portable and and laboratory PIDs have been sold throughout the world. Dr. Jack Driscoll, inventor of the PID, received the AIHA Edward Baier award in 2017 (https://bit.ly/2rRG6M8) for the development of the PID for industrial hygiene measurements. More than 50 United States Environmental Protection Agency and Occupational Safety & Health Administration (OSHA) methods have been published in the Federal Register. Many states have adopted these methods for VOC’s.

Principle of Operation
The process occurs when a molecule absorbs light of sufficient energy to ionize a molecule see below:

RH + hv = RH+ + e-
where
RH is a molecule of gas

hv is a photon with an energy greater than or equal to the ionization potential of the molecule RH.

The ultraviolet lamp generates photons that ionize the molecule RH (above) and generates positive ions. An accelerator electrode (positively biased) pushes the ions, to the collector electrode where the current (proportional to concentration) is generated, amplified and displayed on the digital meter.
