Infrared spectroscopy, with its high specificity, is an ideal way to identify gas chromatographic fractions (1), but the size of sample available as a column effluent often demands the use of micro techniques for obtaining spectra. The present Trick describes a method for collecting and obtaining the infrared spectra of gas chromatographic fractions in the 10 to 100 μg range. Although it is a micro technique, the equipment is simple, inexpensive, and can be made in most laboratory machine shops. No beam condenser is required, and the spectra may be scanned on a "table top" infrared spectrophotometer.
