Intended Use

For IN VITRO diagnostic use in the quantitative determination of Chloride in serum using manual or automated applications.

 

Method Principle

Chloride ions present in the serum sample interact with Ferric ions in dilute acid to form a yellow chloro-complex with maximum absorption at 340nm. The intensity of the color thus produced is directly proportional to the concentration of the chloride ion in the serum sample. The reaction volume illustrates the reaction that occurs in this method.
