摘要：

The potential applicability of cryotrapping gas chromatography-Fourier transform infrared spectrometry in environmental analysis was studied. First results of on-the-flight measurements on pesticides and polynuclear aromatic hydrocarbons show detection limits in the 100-500 pg range. The low-temperature spectra obtained appear to be closely comparable to conventionally recorded spectra. Library search procedures based on existing solid-phase spectra appear to be useful.
