1. Apparatus for the automated sequential formation and analysis in turn of each of a series of substance-containing recovery fluid volumes through use of automated fluid volume supply apparatus and automated fluid volume analysis apparatus and including, separation chamber means having an inlet and an outlet, means for automatically flowing substance-containing carrier fluid volumes in turn from said automated fluid volume supply apparatus into said separation chamber means through said inlet, means for concomitantly automatically controlling the temperature of said separation chamber means to be effective to vaporize said carrier fluid and ineffective to vaporize said substance with resultant separation of said substance from said carrier fluid at a separation zone in said separation chamber, said separation chamber means including means for accumulating the thusly separated substance in a band at said separation zone, means for flowing the substance-free carrier fluid out of said separation chamber means through said outlet, means for correlating the flow rate of said substance carrier fluid into said separation chamber means and the temperature of said separation chamber means to determine the location of said accumulated substance band in said separation chamber means, means operable subsequent to the flow of each of said substance-containing carrier fluid volumes into said separation chamber means to automatically flow a substance recovery fluid volume from said automated fluid volume supply apparatus into said separation chamber means through said inlet, means for concomitantly automatically controlling the temperature of said separation chamber means to be ineffective to vaporize said substance recovery fluid or said substance with resultant pick-up of the thusly accumulated substance band by the substance recovery fluid and means for automatically flowing at least a portion of each of the substance-containing recovery fluid volumes in turn to said automated analysis apparatus for analysis thereby.
