Dry tests: construction, principle of action, and application

Abstract

A short description of dry test constructions, chemical principles of action are presented. An example of statement of reflection spectra of described dry tests were shown. For this spectra the best region for determination of analytes by reflectance were selected. The results of a few examples of determination pollution in water an din milk were shown. The all determination had been carried out by dry tests. The reading was performed by comparison with a color scale. In case of flood water analysis determination had been carried out by comparison with a color scale, reflectometrically and by means of classic colorimetric methods.
