ABSTRACT:
The functions of a gas chromatograph depending on the advancement stage of the analysis can be at least partly controlled by detecting the data relating to the carrier feeding conditions (pressure and/or flow) in a position upstream the injection point of the sample to be analyzed, and by measuring the variations occurring in the conditions after the sample injection. This method is particularly convenient for the analysis of samples with high volumes of eluent, and one of its preferred embodiments foresees the use of a pressure sensor in a point of the carrier feeding duct or, alternatively, of a flow sensor positioned between two points of the feeding duct.
