HPLC Chiral Separation of Tramadol Enantiomers on Cyralis CM Column

July 13, 2026

HPLC Method for Analysis of Tramadol on Cyralis CM Column by SIELC Technologies

High Performance Liquid Chromatography (HPLC) Method for Analysis of Tramadol.

Tramadol is a narcotic analgesic with the chemical formula C16H25NO2. It is used to manage severe pain. It is a synthetic codeine analogue. The way it works is similar to opioids, such as morphine and codeine due to it acting on specific opioid receptors. An overdose on the drug can cause acute liver failure. Tramadol, also known as Ultram and other brand names, is a synthetic opiate used to treat moderate to severe pain. The painkilling effects of Tramadol last for about 6 hours. You can find detailed UV spectra of Tramadol and information about its various lambda maxima by visiting the following link.

This application describes a normal-phase chiral HPLC method for the separation of Tramadol enantiomers using SIELC’s Cyralis CM chiral column. Cyralis CM is a cellulose-based chiral stationary phase (CSP) designed for enantiomeric separations, optical purity testing, chiral impurity analysis, and stereoisomer characterization in pharmaceutical, chemical, agrochemical, and fine chemical applications. For best results, the sample should be prepared fresh for analysis.

Tramadol can be retained and analyzed using the Cyralis CM stationary phase column. The analysis utilizes an isocratic method with a mobile phase consisting of Hexane, IPA, and 2-(dimethylamino)ethanol. Detection is performed using UV.

UV/Vis.: λmax: 220, 270 nm

For optimal results in HPLC analysis, it is recommended to measure absorbance at a wavelength that matches the absorption maximum of the compound(s) being analyzed. The UV spectrum shown can assist in selecting an appropriate wavelength for your analysis. Please note that certain mobile phases and buffers may block wavelengths below 230 nm, rendering absorbance measurement at these wavelengths ineffective. If detection below 230 nm is required, it is recommended to use acetonitrile and water as low UV-transparent mobile phases, with phosphoric acid and its salts, sulfuric acid, and TFA as buffers.
For some compounds, the UV-Vis Spectrum is affected by the pH of the mobile phase. The compound was dissolved in ethanol. This analysis was done with the mobile phase of hexane, IPA, and TFA.

This compound was diluted in a mixture of water and acetonitrile. The method was done with a mixture of water, acetonitrile, and a sulfuric acid buffer.

HPLC Method for Tramadol, Tramadol hydrochloride on Primesep SB by SIELC Technologies


High Performance Liquid Chromatography (HPLC) Method for Analysis of Tramadol, Tramadol hydrochloride.

FlipLC™ is an alternative method to avoid the interference of most of the contaminants by the use of an isolation column and a high pressure switching valve before the separation column. This method allows sample cleaning and analyte separation in one automated process. The isolation column and the separation column should have orthogonal retention characteristics to operate efficiently in this setup. Mixed-mode columns with reverse phase and ion-exchange characteristics were used in this analysis.

Application Column

Primesep SB

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.
