#AIHceEXP: The @pidgirl experience

#AIHceEXP May 20-23 2018 Philadelphia, PA

The primary reason that we attend the #AIHceEXP annually is to exhibit our suite of gas detection products.

Featured real-time detection products included: 

First level screening tools for rapid identification of the source of the spill/smell/area of concern-Total VOC monitoring: Model 102+ PID with multi-sensor options and Model 115 FID





Second level screening tools for separation of components where general knowledge of types of contaminants/chemicals are being used: Continuous monitors: Model 112
(PID/FID or TCD).
Hand-Held GC: Model 121

Third level tools for sophisticated monitoring:
Model 312 Portable Gas Chromatograph with PC on board and dual detector capability-ideal for applications where the user can eliminate sending samples to the lab
Model 301C: Process Analyzer for 24/7 data reporting of complex matrices.

Nearly everyone who came by my booth at #AIHceEXP wanted to know what makes our PID lamps last so long? How do we have an 11.7eV lamp that operates for 500 hours? The answer is simple: We developed the technology and have, since 1973, had a reputation in the gas and vapor detection industry for manufacturing durable, accurate and reliable instrumentation. While there are commercially available products that are in smaller and in sleeker packages, our competitively priced PID remains the most sensitive and selective on the market. Interested in trading in your old PID and upgrading to an HNU? Contact me today.

My father, Jack Driscoll, and I are also members of the Real-Time Detection Systems Committee which meets in-person at this meeting. This is a very active committee and although there was a 6am start time for this group, the room was full! Additionally, I moderated an education session for the Real-Time Detection Systems Committee programming titled: Studies in Real-Time Detection Systems: Monitoring Exposures. This session had over a hundred people at it and was broadcast live to the virtual conference attendees. One of the speakers in the session, Phil Smith, who is a longtime colleague and friend of our family, was inducted as an American Industrial Hygiene Association (AIHA) Fellow at the Mark of Excellence Breakfast!

I've been Chair of the AIHA Teen Workplace Safety Task Force since September 2017 and we had our first in-person meeting at #AIHceEXP. This is a grass-roots effort that is under the AIHA Government Relations umbrella. We are currently seeking additional task force members and if educating teens in your community about workplace safety and taking legislative action in your state to require that teens receive workplace safety as part of their educational curriculum in schools peaks your interest, please contact me to learn more.

AIHA excels at organizing and facilitating networking events! From the Catalyst Merry-Go-Round to the MSA Power Hour, I logged lots of networking at this conference!

I even managed a quick visit to LOVE Park on my way between #AIHceEXP social events!

ABSTRACT BODY:  Abstract: Cutter and others (1) described Hydride Generation (HG) with Gas Chromatography (GC)/Photoionization Detector (PID) with a liquid nitrogen concentrator more than twenty-five years ago for part per billion (ppb) detection of metalloids such as As, Sb and Se, in natural waters. These early papers on HG/GC/PID (1 ) used a liquid nitrogen trap to collect the AsH3 from the hydride generator. The trap was heated to drive off the concentrated AsH3 sample into the GC. Cutter (2) has continued his work on the analysis of As in natural waters with GC/PID and is able to detect 0.75 parts per trillion (ppt) of As. An additional advantage of this PID method is that it could also be used to detect organoarsenic compounds. Driscoll and Maclachlan described a modified HG/GC/PID method for the analysis of ppb levels of arsenic in drinking water and apple juice at the American Chemical Society meeting in New Orleans in 2013 (3). We have used that method and developed modifications and significant improvements including the elimination of the liquid nitrogen concentrator and detection of sub ppb levels of As. The advantages of the new HG/GC/PID analytical method are that it does not use liquid nitrogen, is easy to use, can determine inorganic arsenic (As+3 & As+5), does not require a high level of operator training and the capital cost is a fraction of Graphite Furnace Atomic Adsorption (GFAAS), or LC/ICP/MS system. This HG/GC/PID method will be described in detail in this paper. References: 1 Cutter LS, GA Cutter, San Diego McGlone, Anal Chem 63,1138 (1991) 2 Cutter, G. A., and Cutter, L. S. (2006).
