ABSTRACT SYMPOSIUM NAME: SCI-MIX and General PostersABSTRACT SYMPOSIUM PROGRAM AREA NAME: [ENVR] Division of Environmental ChemistryCONTROL ID: 2253367PRESENTATION TYPE: Poster TITLE: A new technique for ppt levels of mercury in air and  waterAUTHORS (FIRST NAME, LAST NAME): John N.

Abstract: 
We reported recently that the photoionization detector (PID) with a 10.6 eV lamp responds to mercury (Hg) with detection limits of 10 ppb. The PID is a non-specific method for Hg since it also has a strong response to VOC’s. Other non-specific methods like UV absorbance and atomic fluorescence use a gold pre concentrator (GPC) to collect Hg by forming a Au/Hg amalgam at room temperature, purging to remove water and VOC’s t…

ACCEPTED for Presentation at the American Chemical Society 250th National Meeting in Boston August 16-20, 2015 on the Analytical Chemistry Division Program Track


ABSTRACT SYMPOSIUM NAME: Advances in Analytical Separations, Organized by Jennifer Maclachlan ABSTRACT SYMPOSIUM PROGRAM AREA NAME: [ANYL] Division of Analytical Chemistry CONTROL ID: 2260931 PRESENTATION TYPE: Oral  TITLE:Detection of ppb levels of arsenic in beers and wines
AUTHORS (FIRST NAME, LAST NAME): John N. Driscoll1, Jennifer L. Maclachlan1 INSTITUTIONS (ALL): 1. PID Analyzers, LLC, Sandwich, MA, United States. 

ABSTRACT BODY: Abstract: Government regulations have resulted in the discontinuation of many
 arsenic compounds in the USA. Still, there may be leftover supplies of arsenical pesticides in farms 
or in the fields that continue to represent residual risk. In fact, we have investigated a series of 
California wines using hydride generation/gas chromatography/photoionization detection 
(HG/GC/PID) for the analysis of triva…

Add photoionization detection capabilities to your GC

Here's a recent installation of our photoionization detector (PID) onto an HP 5890. The PID detector upgrade installation is commonly done by the end user but we had the opportunity to upgrade this client's equipment at our place. Learn more about our PID capabilities below or contact us for a quote using this link. For technical application questions, contact sales@hnu.com.
