✦ Synopsis

A method has been developed for obtammg and stormg the complete Fourier transform spectrum, of a sample m a flowmg stream m only 19 s A resolution of 4 cm-l IS recommended The determmahon of o-xylene m xylol was employed as a test system, usmg hexane as a tamer and dduent m all the expenments A classlcal hqmd flow cell and a demountable flow-through cell were compared The best hmlt of detectlon obtamed was 0 01% (v/v) The effects of flow-rate and lnjectlon volume were studled for the two cells used The relative standard devlatlon (0 4% o-xylene, n = 5) was ca 1%
