The arsenic test strips are suitable for measuring arsenic in water, soil extracts, pharmaceutical products, prepared biological specimens and liquid foods. Within this MQuant Arsenic test, test strips are used in combination with additional reagents. Arsenic is liberated from the sample by adding zinc powder, a solid acid, and - for the elimination of interfering sulfide ions - an oxidizing agent. On the reaction zone of the test strip a yellow-brown dye is formed. The concentration of arsenic(III) and arsenic(V) are measured semiquantitatively by visual comparison of the reaction zone of the test strip with the fields of a color scale. Please also not our MQuant Arsenic test (117917) for higher concentration measurements. The test strips are perfect for pre-testing a sample in an economic and quick way to estimate the arsenic concentration and a possible dilution factor prior to using a quantitative method such as a Spectroquant test.
Method: colorimetric with test strips and reagent 0.005 - 0.010 - 0.025 - 0.05 - 0.10 - 0.25 - 0.50 mg/l As MQuant®
