INTERFERENCE-RESISTANT TEST DEVICE FOR DETERMINING A PEROXIDATELY ACTIVE SUBSTANCE IN A TEST SAMPLE AND METHOD FOR PREPARING IT

摘要

A test device for determining the presence of a peroxidatively active substance in a test sample, and a method for making it, are disclosed. The device comprises a carrier matrix incorporated with a Co (III) complex and a fused ring compound having the structure in which R is the residue of a substituted or unsubstituted carbocylic or heterocyclic ring system, the ring having 4 to 7 atoms. The method comprises contacting the matrix with a first reagent mixture of an organic hydroperoxide and an indicator, then contacting the matrix with a second reagent mixture containing the Co(III) complex and fused ring compound.
