HPLC Analysis of Drug Tramadol and Related Impurities on Coresep 100 Mixed-Mode Column

Application description

Tramadol is an opioid analgesic. It is used to treat moderate and severe pain. It is often combined with Acetaminophen to improve the efficacy of tramadol in relieving pain. It is converted in the body to Desmethyltramadol. The available dosage forms include liquids, syrups, drops, elixirs, effervescent tablets and powders for mixing with water, capsules, and tablets. This includes extended release formulations, suppositories, compounding powder, and injections. We developed a method for tramadol and related impurities on the Coresep 100 mixed-mode column. Tramadol is a hydrophobic basic compound. Tramadol and related impurities are retained and separated based on reversed-phase and cation-exchange mechanism. The retention time, resolution and peak shape are controlled by the amount of organic, buffer pH and buffer concentration. Various mobile phases can be used with Coresep 100 column to accommodate multiple detection techniques. UV transparent buffers can be replaced with volatile buffers for MS, ELSD or CAD detection. Core-shell mixed-mode columns provide great combination of unique selectivity, speed and efficiency.
