PROBLEM TO BE SOLVED: To provide a single-use disposable article for determining the concentration of thiol compounds in a sample of fluid, and a method of manufacture and a method of application for the article.SOLUTION: Provided is a single-use disposable article for determining the concentration of thiol compounds in a sample of fluid, the article comprising: (a) a matrix comprising at least one absorbent material, the matrix being capable of absorbing the sample; and (b) an amount of a detection reagent, the amount of the detection reagent being capable of providing, during a period of time after at least a portion of the amount of the detection reagent has been contacted with at least a portion of the sample, a signal indicating the concentration of thiol compounds in the sample.
Abstract:
PROBLEM TO BE SOLVED: To provide a dry test piece for calcium measurement with which a measurement error become small and on which an influence of magnesium in a sample is reduced.SOLUTION: A dry test piece 1 for calcium measurement includes a support 2, a reagent layer 4 provided on the support 2, and a reagent holding layer 5 provided on the reagent layer 4 and contains, as reagent components, an o-cresolphthalein complexone, a magnesium selective masking agent, and a pH buffer for buffering the pH of a reaction environment of the o-cresolphthalein complexone with calcium to 10.0-11.0. These reagent components are present in either the reagent layer or the reagent holding layer or the both layers.
