ABSTRACT:
A composition, method and test device for determining the divalent cation concentration or estimating the specific gravity of a test sample are disclosed. The method utilizes a test device comprising a test pad, wherein the test pad includes a carrier matrix incorporating a reagent composition capable of interacting with divalent cations present in the test sample to produce a detectable and measurable response that correlates to the divalent cation concentration or to the specific gravity of the test sample. The reagent composition, comprising a metal-sensitive triphenylmethane dye; a buffer; an optional chelating agent; and suitable carrier, is incorporated into a carrier matrix to provide a test pad of a device useful in a divalent cation assay or a specific gravity assay of a test sample.
