METHOD OF SEPARATING MONOLAYER OF SUBSTANCE Russian patent published in 2014 - IPC G01N30/90 

FIELD: chemistry.

SUBSTANCE: invention relates to field of analytical chemistry and is intended for separation of monolayer of substance in order to carry out further analysis of substance properties. Method of separating monolayer of substance includes application of liquid sample with dissolved in it substance of the start line on chromatographic plate, which contains a layer of sorbent. Several drops of substance sample of equal concentration, but of different amount are applied on the start line, starting with minimally possible amount; eluent is passed through plate for separation. After that, separated spots of substance samples are registered on plate and diameter of spots of substance sample on the start line and height of peak of each spot are measured. After that, curve of dependence of height of spot peak on spot diameter on the start is built and points of curve breaks are fixed. Detection of sample spots with substance monolayer is carried out by the character of curve from the first minimal sample to sample, corresponding to the point of the first curve break.

EFFECT: separation of monolayer of analysed substance is ensured, increase of accuracy of substance chromatographic analysis, increase of accuracy of analysis of substance properties, possibility to predict application of substance in different fields of industry.
