摘要:
An integral multilayer analytical element for the analysis of ammonia or an ammonia forming substrate in a liquid sample is disclosed. The element comprises a transparent support on which an indicator layer for ammonia, a liquid blocking layer, a reagent layer incorporated with a reagent which may react with the substrate to form ammonia, and a spreading layer, are integrally superposed in this order. The improvement is that the liquid blocking layer is made of a porous material which is permeable to ammonia but substantially impermeable to liquids.
摘要:
In a multilayer analysis film for detecting hydrogen peroxide by dry process which comprises a support and a reagent layer having contained therein a color indicator composition comprising peroxidase and a substance capable of causing a optically detectable change in the presence of hydrogen peroxide and peroxidase, the color indicator composition is characterized by further containing specific pyrogallol derivatives. Such pyrogallol derivatives improve stability during storage of such a multilayer analysis film.
摘要:
A dry-type analytical element suitable for measuring the activity of alanine aminotransferase in a liquid sample, characterized by incorporating a dye capable of absorbing the electromagnetic waves of 400 to 500 nm into at least one water-permeable layer. The coloring sensitivity of the dry-type analytical element does not increase substantially even under a fluorescent light, and thereby, an accurate measured value can easily be obtained.
