@pidguy's true story of developing & marketing an environmental instrumentation company: a forty year perspective

Join us on the ACS Division of Small Chemical Businesses Program Track at the ACS National Meeting in New Orleans to hear @pidguy's *true story* 26 - Developing and marketing an environmental instrumentation company: A forty year perspective

Jack N. Driscoll, PID Analyzers, LLC, Sandwich, MA 02563, United States

HNU Systems, Inc., was founded by Driscoll & Spaziani in December 1973, intending to develop a new technology, photoionization detection (PID), for the analysis of environmental pollutants. We went to NIOSH in Cincinnati to explore potential uses of PID in industrial hygiene. During our visit, a scientist at NIOSH said, "If you had a portable instrument that would measure vinyl chloride monomer (VCM) at 1 ppm, we would be very interested." We went to a gas company the next day to get a lecture bottle of VCM and that afternoon we had a VCM monitor. A working prototype portable (battery operated) PID was built for the AIHCE show and, two months later, we got our …

High resolution gas chromatography (HRGC) with a capillary column (50,000 to 100,000 theoretical plates) is an efficient and effective means for separation of a complex mixture of chemicals in the ambient air. Since retention times are used for identification, either a second column with a different polarity or the ratio of two detectors are used to confirm the …
