FIELD: chromatography. SUBSTANCE: method of determination of thickness of organic binder layer on the base-adsorbent consists in the fact that ground adsorbent is placed in the chromatograph thermostated column, equimolecular quantities of model compounds having structural fragments similar to structural fragments of organic binder are proportionated in succession into the column in the order of increasing of the molecular spaces of model compounds at Tb+n, where Tk is the model compound boiling point, n=0 to 65 C, chromatographic peaks are recorded, adsorption isotherms, concentration of model compound in gas close to the maximum one, monolayer volume and specific surface of adsorbent, thickness of model compound monolayer on the adsorbent surface are determined, and the thickness of organic binder on adsorbent is determined according to the additivity principle with due account made for the structural-group composition of organic binder. EFFECT: facilitated procedure. 4 tbl
