PROCEDURE DETERMINING CONCENTRATION OF COMPONENTS IN MULTICOMPONENT SOLUTIONS

摘要

FIELD: control over technological parameters of multicomponent solutions. SUBSTANCE: refractive indices n1 and n2 of sample of analyzed substance on wave lengths lambda1 and lambda2 correspondingly are measured. Values of refractive indices n1 and n2 are measured in addition for same wave lengths in substance having composition close to analyzed substance but not containing determined component. Then difference DELTAn1 = |n2-n1| and average value of difference are found and ratio is determined. This ratio is employed to determine sought-for concentration. EFFECT: possibility for selective determination of concentration of multicomponent solutions with required degree of accuracy without change of parameters of solutions themselves. 2 dwg
