HPLC Method for Analysis of Cocaine
Cocaine, also known as coke, is mostly used as a recreational drug. It is a strong stimulant. The drug’s most common appearance in powder form is a salt, usually cocaine hydrochloride. Due to Cocaine rapidly metabolizing in the body, so if it’s ingested/inhaled, its concentration in urine usually does not exceed 10% that of its principal metabolite, benzoylecgonine. Primesep 200, a reverse phase column, contains embedded acidic ionizable groups and can retain Cocaine. The method is UV compatible and can be used as a general approach for analyzing similar compounds.
