Gas Chromatography: Environmental

A poster session focusing on gas chromatography (GC) and the environment was held on Tuesday afternoon of Pittcon 2009 in Chicago.

A poster session focusing on gas chromatography (GC) and the environment was held on Tuesday afternoon of Pittcon 2009 in Chicago.

Recommended by LCGC “GC Connections” columnist John Hinshaw, topics in the session ranged from fuel oxygenates in soil to the determining of mercury in natural waters.

With so much concern about the environment in today’s society, it is no wonder why this was a well-visited poster session for conference attendees.

Gary Burce of Varian, Inc., Walnut Creek, California, presented a poster entitled “Optimized Data Handling for Automatically Calculating the Hydrocarbon Index (HI) of “Produced Waters” from Gas Chromatographic Analysis”Burce’s co-authors on the poster were Graham Shelver, Charles Van Dortmond, and Bob Lott. According to the poster, oil and gas extraction from subsea wells produce large quantities of hydrocarbon contaminated water which are disposed of directly into the oceans. Determination of the Hydrocarbon Index (HI) is required to meet environmental legislation.

Another interesting poster presentation was given by Ali Sarafraz Yazdi of Ferdowsi University of Mashhad, Chemistry Department, Faculty Of Sciences, Mashhad, Khorasan, Iran. The subject of Yazdi’s poster was the “Determination of Mercury (II) in Natural Waters by Phenylation Using Single-Drop Liquid Phase Microextraction - Gas Chromatography”According to the poster, the purpose of the work was to develop a simple, rapid, sensitive and accurate method for the simultaneous derivatization and pre-concentration of mercury (Hg2+) and the determination of the derivative, phenyl-mercury, in natural water samples using gas chromatography-flame ionization detector.

Different poster session will presented through Thursday afternoon at Pittcon.
