The Tuesday afternoon session on gas chromatography (GC) applications includes three talks from instrument vendors.

The first presentation, by Ulrich Gokeler of Siemens, discusses the benefits of transferring routine GC analyses to automatic on-line measurement. Because an on-line approach enables more frequent measurements and repeatable sample conditions, it may be possible to improve process and quality control as well as to minimize safety concerns. The transfer can also lead to cost savings.

The next talk presents the work of a team of scientists from two organizations: Itsuko Iwai, Dave Randle, and Robert Freeman, all of Frontier Laboratories, and Terry Ramus of Diablo Analytical. The talk will discuss the analysis of phthalates using thermal desorption GC combined with mass spectrometry detection (TD-GC–MS). TD-GC–MS is one of the easiest and most accurate methods for phthalate analysis. The talk will focus on the quantitative analysis of regulated phthalates in a sample with high concentrations of unregulated phthalates.

The final talk of the session, by Shawn Wilson of Inficon, will cover refinery gas analysis with temperature-programmable micro GC. Micro GC instrumentation combines microelectromechanical system (MEMS) technology with a modular GC platform to perform parallel analysis on refinery gas samples, significantly reducing the analysis time from the typical 30 minutes of traditional GC to 3 minutes.

This session will be held from 1:00 to 2:20 pm.
