General description
Method: Colorimetric with test strips and reagent, 0.02 - 0.05 - 0.1 - 0.2 - 0.5 mg/L As, 0.1 - 0.5 - 1.0 - 1.7 - 3.0 mg/L As, MQuant®
The arsenic test strips are suitable for measuring arsenic in water, 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 semi-quantitatively by visual comparison of the reaction zone of the test strip with the fields of a color scale. 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 our Spectroquant® test.
