摘要：

A Simple and effective method of obtaining infra-red spectra of gas chromatographic fractions has been developed making possible rigorous identification with microgram quantities. After gas-liquid chromatographic injection, the seperated components which emerge from the column are passed through a heated line via a stream splitter and condensed independently on a glass surface. The isolated component is then transferred to KBr for microdisc preparation. The method of sample transfer described gives a high recovery, eliminates many possible sources of contamination and yields high quality infra-red spectra for 1-10 μg samples. The results of the technique are illustrated with a number of typical spectra. © 1968.
