Tests for semi-quantitative determination (color charts)

Sigma-Aldrich offers easy, inexpensive and quick to use semi-quantitative methods for analyzing a large variety of analytes in water, including metals (such as iron, arsenic or chromium), anions (e.g. cyanide, chloride) and organic substances (e.g. ascorbic acid, formaldehyde or phenol).

Each kits contains the reagents, detailed instructions and a color chart needed for the analysis. Some test strips can be used without additional reagents to perform direct semi-quantitative determinations within a few minutes.
