FIELD: chromatography. SUBSTANCE: invention is intended for analysis of multicomponent mixtures of various composition. Metering cock incorporates case assembled from sections and having two through axial passages, seven pairs of radial holes arranged uniformly and diametrically in opposite sides of case and mobile shutting members manufactured in the form of hollow tubes with caps in center and holes on both sides of caps put into axial passages. It is used for simultaneous injection into chromatographic column and joint analysis of fixed amount of three samples of various substances different in volume. Mobile shutting members are interconnected by means of vessel for gas metering. Caps in center of each shutting member have radial holes and annular grooves over outer diameter for metering of two different liquids. EFFECT: simplified design and improved functional reliability. 2 cl, 1 dwg
