FIELD: instrument engineering.
SUBSTANCE: invention relates to gas chromatography and can be used for efficient rapid analysis of complex mixtures of substances of natural and technogenic origin. Microchromatograph comprises replaceable independently controlled analytical modules for analysis of components of complex mixtures, each of which contains a temperature-controlled microchromatographic column, made on flat plates with channels for sorbent, made by micro milling, thermostated planar microdispenser of the analyzed sample and the thermostated detection system, characterized in that the thermostatically controlled microchromatographic column is composite and includes two microchromatographic columns on the plane, wherein the analytical module is additionally equipped with at least one small-size electric pneumatic distributor for control of composite columns.
EFFECT: high sensitivity, higher separation capacity and shorter analysis time.
