| Abstract: | The combined gas chromatography with infrared spectrometry for the detection and i-dentification of mixtures in volatile organic compounds is described.Various experimentalparameters such as volume and dimensions of the interface lightpipe,the chromatographicoperating conditions,the optical design and selection of detector are evaluated.The selectionof experimental parameters for the purpose of achieving best sensitivity and chromatographicresolution is proposed. The high sensitivity and resolution of a GC/IR system are expected.The results of application of the technique developed to separate butyl esters of fatty acidsfrom bacteria metabolite are given. |
