Description

Description générale

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 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.

Application

• 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 AppliedSciences analyzed the handling of arsenic in library materials.Arsenic-containing pigments in library materials are a source of danger forinstitutional staff, conservators, scientists, and users. Over 300 volumes withsuspicious green book components were analyzed using both XRF and Ramanspectroscopy, with arsenic compounds being detected in around half of them. TheXRF device is mobile and effective, it yields reproducible data and can detect amultitude of elements such as arsenic, lead, and mercury. However, it emitsradiation and is limited to small spots. Special training for operating thedevice as well as for interpreting the results is needed. A rapid test based onbromide test strips and the [TM=“MQUANT”] test kit were then evaluated. Whencomparing the rapid test kits, the [TM=“MQUANT”] test kit appears to be moresuitable than the bromide test paper as it includes all necessary accessoriesand helps minimize the hazard potential for users. The [TM=“MQUANT”] test kitmay be suitable for initial in situ examinations, after training andinstruction of the archive staff, being fairly accurate, ready-made, easy tohandle, and suitable for testing surfaces.
