HPLC Analysis of Illicit Drug Heroin on Coresep 100 Mixed-Mode Column

Application description

Heroin is an opioid recreational illegal drug. It is Schedule I controlled substance. Heroin is hydrophobic and basic in nature. It is retained on mixed-mode Coresep 100 HPLC column by combination of strong hydrophobic and strong cation-exchange mechanisms. This method is robust, fast and reliable with good retention and peak shape for highly hydrophobic and basic molecule. Retention time is controlled by the amount of acetonitrile, buffer concentration, and buffer pH. The method can be applied to the analysis of other illegal drugs in biofluids and formulations. The method is isocratic and fully compatible with LC/MS.
