METHOD OF CODEINE IDENTIFICATION Russian patent published in 2014 - IPC G01N33/15 G01N30/90

Abstract RU 2523408 C1

FIELD: chemistry.

SUBSTANCE: method of codeine identification includes separation of mixture components by a method of thin-layer chromatography with separation of a chromatographic zone of codeine by a reagent of Dragendorff, and quantitative determination of codeine is carried out in an area of its manifested zone directly in a solid phase by measuring diffusion reflection coefficient at a wave length of 520 nm.

EFFECT: reduction of time of identification and quantitative determination of codeine, reduction of the process labour consumption, reduction of a probability of the target component loss.
