Abstract:
Sampling is often the most difficult part of an analytical method even for micro and Fast Gas Chromatography. In some cases the analytes of interest cannot be separated and measured with a column system that can survive the balance of the sample matrix. Purity analysis of Polyethylene Pellets is an excellent example. The solution is to heat the pellets and drive the target analytes into the headspace gas. The autosampler using a gas tight syringe can then sample and introduce the resultant sample into the GC. This paper will describe the system and the methods developed for this analysis.
