MULTICHANNEL CABLE-SCANNER COLORIMETRE FOR ANALYSING MULTICOMPONENT AQUEOUS SOLUTIONS Russian patent published in 2012 - IPC G01N31/20 B01L3/02 

FIELD: chemistry.

SUBSTANCE: multichannel cable-scanner colorimetre for analysing multicomponent aqueous solutions contains a set of selective indicator test forms based on selective chromogenic analytical reagents. The colorimetre is adapted to perform drop analysis, for which the set of selective indicator test forms, which are meant for carrying out reactions of the analysed solution with chromogenic reagents of the test forms, is placed in a reactor block fitted with a multichannel apparatus for batching and feeding samples, which ensures independent drip feed of the analysed solution into each colorimetre channel having a selective indicator test form. The set of indicator test forms is in form of a test slide. The colorimetre has an electronic module for controlling operation of the reactor block and the multichannel apparatus for batching and feeding samples, connected through an interface to a personal computer. The colorimetre has a scan converter of the analytical response signal of the selective indicator test forms which is a slide scanner.

EFFECT: high accuracy, sensitivity and reliability of analysis.
