117927 Arsenic Test Metode: kolorimetrik dengan strip tes dan reagen 0.005 - 0.010 - 0.025 - 0.05 - 0.10 - 0.25 - 0.50 mg/l As MQuant®

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.
