Dry tests: construction, principle of action, and application

摘要

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