EM Quant® Arsenic Test (sensitive) EMD Chemicals Inc.
EM Quant® Arsenic Test (sensitive), Catalog No. 17926/11. MethodWhen zinc and sulfuric acid are added to compounds of arsenic(III) and arsenic(V), arsenic hydride is liberated, which in turn reacts with mercury(II) bromide contained in the reaction zone of the analytical test strip to form yellow-brown mixed arsenic mercury halogenides. The concentration of arsenic(III) and arsenic(V) are measured semiquantitatively by visual comparison of the reaction zone of the analytical test strip with the fields of a color scale. 2. Measuring Range and Number of Determinations
3. ApplicationsSample Material: 4. Influence of Foreign SubstancesThe concentrations of foreign substances given in the table lie below the limit at which the determination is interfered with:
5. Reagents and Auxiliaries
Package Contents: 6. PreparationSamples containing more than 0.5mg/l As3+/5+ must be diluted with distilled water. Alternatively, it is also possible to use the EM Quant® Arsenic Test Cat. No. 10026/1 (measuring range 0.1-3mg/l As3+/5+). 7. Procedure
