Abstract
A method has been developed for obtaining and storing the complete Fourier transform spectrum, of a sample in a flowing stream in only 19 s. A resolution of 4 cm −1 is recommended. The determination of o-xylene in xylol was employed as a test system, using hexane as a carrier and diluent in all the experiments. A classical liquid flow cell and a demountable flow-through cell were compared. The best limit of detection obtained was 0.01% (v/v). The effects of flow-rate and injection volume were studied for the two cells used. The relative standard deviation (0.4% o-xylene, n = 5) was ca. 1%
