Direct thiocyanate method

Monoreagent

Quantitative determination of Chlorides on serum, plasma and urine according to mercury thiocyanate reaction.

Chloride is the main inorganic anion of extracellular liquid: it is extremely important for the regulation and maintenance of hydro-electric balance, for acid base balance and for a regular osmolarity. Stomach acids contain high levels of chlorine, mainly because of the presence of hydrochloric acid, essential for protein digestion and for the defense against food bacteria. Chlorine is absorbed especially in the proximal portion of the small intestine, through an exchange with bicarbonates.
