[Determination of thiocyanate ions in saliva by coupling high performance liquid chromatography with specific electrode].

An electrochemical method for determination of thiocyanide ions in saliva was established. The procedure involves coupling high performance liquid chromatography (HPLC) on bounded silica gel (in order to eliminate the interference of some ions) with specific electrode. This method is sensitive, precise, rapid and requires only few samples. It offers a great interest in toxicology for the detection of smoking exposure.
