Rugged isocratic LC-UV method for the analysis of 16 cannabinoids in hemp and cannabis samples

27 Jul 2020

This application note outlines a simple and robust method for the detection and quantitation of 16 cannabinoids in hemp and cannabis samples using an isocratic HPLC method coupled with UV detection. Baseline separation of all 16 cannabinoids, including that of the critical pair Δ9-THC and Δ8-THC, was successfully achieved using a Selectra® C18 column. Examples of hemp flower and oil samples analyzed using the analytical method are also presented. With the widespread legalization of hemp and cannabis, this simple method will be beneficial for any research facility wanting to implement regulatory testing without fighting the wide variation of the matrices and interfering compounds (i.e. terpenes, pigments, etc.) in the diverse products that exist in the marketplace.

UHPLC and HPLCHigh performance liquid chromatography (HPLC) and ultra high performance liquid chromatography (UHPLC), also known as UPLC, are analytical techniques used to separate, identify and quantitate components of complex mixtures including biological samples such as proteins and lipids as well as chemical mixtures of pesticides, drugs and oils. Both techniques are liquid chromatographic methods but differ by operating pressures (HPLC < 6000 psi < UHPLC ). Components of HPLC and UHPLC systems include columns, detectors, pumps, autosamplers and column heaters. Explore a range of UHPLC and HPLC columns for your specific sample needs including reverse phase, normal phase, ion exchange, HILIC, ion exclusion and size exclusion columns. For more specialized HPLC, explore FPLC, countercurrent LC and simulated moving bed systems.

The two major instrument classes are single-beam or double-beam spectrophotometers. More specialized equipment includes colorimeters, spectroradiometers and refractometers. Portable and microvolume spectrophotometers are also available. For the modular spectroscopy lab, explore a range of light sources for combination with a spectrograph/spectrometer and optics.

It is widely used in fields like biochemistry, pharmaceuticals, and environmental analysis. By exploiting differences in the interaction of substances with a stationary phase and a mobile phase, chromatography enables precise purification and quantification of compounds. Whether you're working with complex biological samples or industrial chemicals, chromatography is essential for obtaining high-quality results.
