An integrated GC/FT‐IR system for the analysis of environmental pollutants

An integrated gas chromatography/Fourier transform infrared spectrometry (GC/FT‐IR) system developed for the analysis of environmental pollutants is described. The versatility of the system allows the utilization of many different techniques of sample introduction and manipulation during analysis. The sample can be introduced by direct injection or thermal desorption from an adsorbent cartridge, and can then be separated on one of two capillary columns and detected by FT‐IR or an FID. Cold traps and collection cartridges incorporated in the system permit recovery and additional fractionation of samples. Recovered sample and sample fractions can then be re‐analyzed by GC/FT‐IR or subsequently analyzed by GC/MS or other methods.
