Abstract

The work discusses the influence that different types of liners may have on the transfer of analytes onto the GC column, and hence on the quality of the GC-MS response for their quantitative analysis, at low concentrations. An Optic_3 programmable temperature inlet was used for sample transfer. The analytes were separated on a BPX-5 capillary column, using an Agilent system of a gas chromatograph coupled to a quadrupole mass detector operating in the SIM mode. Selected ions peak areas were determined to assess the GC-MS response. The method linearity, reproducibility, LOQ and LOD are compared for three different liners, using dilutions of a mix of long chain FAMEs standards.
