Abstract:
1. Assembly for determining material properties and/or material concentrations of components of a sample, comprising: (a) a chromatographic separating column adapted to operate with a liquid mobile solvent, said chromatographic separating column having an inside, said inside of said chromatographic separating column having a temperature, and an outside, said outside having ambient temperature and ambient pressure; (b) means for controlling said temperature between room temperature and 250° C; (c) means for creating an increased pressure level which is greater than ambient pressure within said inside of said chromatographic separating column; and (d) a detector having a sample volume, said sample volume adapted to insert said components of said sample, and wherein (e) an interface is provided between said separating column and said detector, said interface comprising: (f) means are provided for heating a zone in the tube within the interface body downstream of the restrictor; and (g) means are provided for transferring said gaseous mobile solvent containing said components of said sample from the outlet into said sample volume of said detector.
