Chromatography Technique Definition

Technique Schema Version 0.34

Technique Definition for Chromatography (A physical method of separation in which the components to be separated are distributed between two phases, one of which is stationary (stationary phase) while the other (the mobile phase) moves in a definite direction. Chromatography, as here constituted, comprises sample introduction, separation, and fractionation. Chromatography is a sample alteration technique that separates complex introduced samples into their component parts; thus it alters, but does not measure or detect, the sample. [IUPAC Orange Book]

    Test Sample Sample Role

    In the case of chromatography, a sample is the mixture consisting of a number of components the separation of which is attempted on the chromatographic bed as they are carried or eluted by the mobile phase. This sample role represents the sample that is analyzed in the given ExperimentStep. [Ettre PAC]
