Applications: Drinking Water, Mineral Water, Curative Water, Spring Water, Surface Water, Ground Water, Surface Water.
Sensitivity is according to the requirements of the WHO for drinking water quality. This test detects 0.005 mg/l Arsenic.
The removal of the interfering sulfide ions is integrated in the test procedure. To minimize the potential danger for the user of the test kit it doesnt use the highly toxic lead acetate for the sulfide removal.
A solid acid substance is used in order to avoid any irritation by a corrosive acid on the users hands.
The unbreakable plastic reaction vessel is more convenient and safe for on-site testing.
During the test procedure the reaction vessel is tightly closed. The developing arsine gas cannot escape and therefore does not harm the user.
The test kit contains a water-proof colour chart which also includes the brief instruction for use in pictograms. Even if there is a lack of knowledge in foreign languages everybody can now handle the test kit.
When zinc powder, a solid acid, and - for the elimination of interfering sulfide ions - an oxidizing agent 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 colour scale.
Arsenic Test Kit
The arsenic test is due to its high sensitivity suitable for the determination of arsenic in drinking water.
