Chromatography

The Chromatography section of the Laboratory performs analyses using Gas, High Pressure Liquid and Ion Chromatography (GC, HPLC and IC). 

 

The gas chromatography group is equipped with chromatographs utilizing a variety of detection systems.  Gas chromatography detectors in the laboratory include dual ECDs, FID/PID, ECD/FID, NPD/FID, FID/TCD allowing this section of the laboratory to perform a variety of different analyses for a wide range of applications.  The GC section performs analyses of industrial hygiene samples for solvent and other organic compounds from various solid sorbent tubes and filters. Analyses also performed by GC include PCB analysis from air, water, soils and wipes, pesticides from various matrices, including TCLP extracts, total petroleum hydrocarbons in the range of diesel fuel, and polynuclear aromatic hydrocarbons. 

 

This section also has the capacity to analyze soils and waters for aromatic volatile organic compounds and total petroleum hydrocarbons in the gasoline range using traditional purge and trap sample introduction. 

 

The HPLC/IC group uses high pressure liquid chromatographic techniques to analyze samples for formaldehyde-DNPH, polynuclear aromatic hydrocarbons from water and air samples, various estrogens, drugs used in patient treatment (ribavirin), and explosives from soil and water.  The HPLC/IC group uses ion chromatography to analyze anions including acid mists (mineral acids and organic acids) from air, soils and waters, and compounds such as sulfur dioxide, ammonia, or ethanolamines from air samples.
