The combined use of infrared spectroscopy and gas-liquid chromatography provides a powerful analytical tool for solving a variety of problems. A simple trapping technique is described which allows 0.4 μl of liquid sample to be examined in the infrared without use of beam condensers.
Examples are presented to show its usefulness in qualitative analysis. The trapping technique is efficient enough to allow quantitative collection for analysis by infrared spectroscopy of two-component, unresolved peaks on the gas chromatograph. Application to dilute water solutions of acrolein
and acetone is given.
