EM Quant® Arsenic Test, Catalog No. 10026Test strips and reagent for the detection and semi-quantitative determination of arsenic ions GeneralThe Arsenic Test can be used for determining arsenic in water, soil extracts, pharmaceutical products, prepared biological specimens and liquid foods. Principle of the methodHydrogen arsenide is formed when zinc and hydrochloric acid are added to test solutions containing tri- and pentavalent arsenic compounds. When a test strip is held in the headspace above the solution, hydrogen arsenide causes the reaction zone, which is impregnated with mercury (II) bromide to turn yellow to brown. Mixed arsenic mercury halides such as AsH2HgBr are formed. Graduation0 - 0.1 - 0.5 - 1.0 - 1.7 - 3mg/l (ppm) As+ Directions
Safety PrecautionsKeep reagent 2 (32% hydrochloric acid) away from the skin. In the event of contact, rinse well immediately with plenty of water. Seek immediate medical attention if substance enters the eye. Influence of AnionsThere is no interference at less than:
Influence of CationsThere is no interference at less than:
Very slight interference is caused by 1mg/l Pd6+ or Cu2+. Package Size 10026 EM Quant® Test strips and reagent Arsenic Test for 100 determinations |
