SEOH Cyantesmo Analytical Test Paper for Determination of Hydrocyanic Acid and Cya.

CYANTESMO is a test paper for the determination of hydrocyanic acid and cyanides in aqueous solutions and extracts. In the presence of HCN, the pale green paper turns blue. It does not react with alkaline cyanide solutions, but is very sensitive to cyanide solutions weakly acidified with sulphuric acid. CYANTESMO reacts intensively in the gas zone just above the level of the solution to be tested. Hexacyanoferrate(II), hexacyanoferrate(III), thiocyanate, thiosulphate and free chlorine interfere. For further information refer to the instructions for use supplied with the paper.Limit of sensitivity: 0.2 mg/l hydrocyanic acid (HCN).
