Descrizione

Descrizione generale

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.

Applicazioni

• Arsenic Pigments in Libraries – Testing Methods, Contaminated Spaces, and Occupational Safety Measures: In a research project, the Bonn University and State Library and the Cologne University of Applied Sciences analyzed the handling of arsenic in library materials. Arsenic-containing pigments in library materials are a source of danger for institutional staff, conservators, scientists, and users. Over 300 volumes with suspicious green book components were analyzed using both XRF and Raman spectroscopy, with arsenic compounds being detected in around half of them. The XRF device is mobile and effective, it yields reproducible data and can detect a multitude of elements such as arsenic, lead, and mercury. However, it emits radiation and is limited to small spots. Special training for operating the device as well as for interpreting the results is needed. A rapid test based on bromide test strips and the [TM=“MQUANT”] test kit were then evaluated. When comparing the rapid test kits, the [TM=“MQUANT”] test kit appears to be more suitable than the bromide test paper as it includes all necessary accessories and helps minimize the hazard potential for users. The [TM=“MQUANT”] test kit may be suitable for initial in situ examinations, after training and instruction of the archive staff, being fairly accurate, ready-made, easy to handle, and suitable for testing surfaces.
