Claim 17

In a method as in claim 10 further comprising, the steps of subsequent to the flow of said substance-containing carrier fluid through said separation chamber and prior to the flow of said substance recovery fluid therethrough, flowing non-substance containing carrier fluid through said separation chamber to compress the thusly separated and accumulated substance band therein to facilitate the pick-up thereof by said substance recovery fluid, and subsequently flowing a purging fluid through said separation chamber to purge the latter of said substance carrier fluid.

Claim 18

In a method for the automated formation and sequential analyses of a series of substance-containing recovery fluid volumes through use of automated fluid volume supply apparatus and automated fluid volume analysis apparatus, the steps of for each of said substance-containing recovery fluid volumes in turn, automatically flowing a substance-containing carrier fluid volume from said automated fluid volume supply apparatus into a separation chamber, concomitantly automatically controlling the temperature of said separation chamber to be effective to vaporize said carrier fluid and ineffective to vaporize said substance with resultant substance-carrier fluid separation at a separation zone in said separation chamber, accumulating the thusly separated substance in a band at said separation zone, flowing the substance-free carrier fluid out of said separation chamber, correlating the flow rate of said substance carrier fluid into said separation chamber and the temperature of said separation chamber to determine the location of said accumulated substance band in said separation chamber, subsequently automatically flowing a substance recovery fluid volume into said separation chamber from said automated fluid volume supply apparatus, concomitantly automatically controlling the temperature of the separation chamber to be ineffective to vaporize said substance recovery fluid or said substance, picking-up the thusly separated and accumulated substance band from the separation chamber in the recovery fluid volume, and automatically flowing at least a portion of the substance-containing recovery fluid volume to said automated analysis apparatus for analysis thereby.

Claim 19
