HPLC Separation of Codeine, Oxycodone, and Hydrocodone


Codeine, oxycodone, and hydrocodone are analgesics with hydrophobic and basic properties. All three compounds are used as strong pain killers and cough suppressant. These compounds are controlled substances according to DEA. We developed a simple method for separation of these narcotics on Primesep 100 and Primesep 200 mixed-mode columns. All three compounds are separated by reversed-phase and cation-exchange mechanism, based on the difference in hydrophobic and ionic properties. This HPLC approach can be used to develop and validate a generic method for analysis of analgesics and other drugs. Compounds are monitored by common detection techniques.

Application Column

Primesep 100

The Primesep family of mixed-mode columns offers a wide variety of stationary phases, boasting unprecedented selectivity in the separation of a broad array of chemical compounds across multiple applications. Corresponding Primesep guard columns, available with all stationary phases, do not require holders. SIELC provides a method development service available to all customers. Inquire about our specially-tailored custom LC-phases for specific separations.
