Residual Solvents and Terpene Analysis

The pre-installed PerkinElmer method for residual solvent and terpene analysis on the GC/MS-HS allows the streamlined lab to run both tests simultaneously.

Cannabis processors utilize extraction to isolate desirable components of the plant, like the terpenes and cannabinoids, and eliminate undesirable parts, like fats and chlorophyll. From oranges to cannabis, terpenes are found in the oils of all botanicals and are often responsible for the distinct flavors and fragrances consumers recognize. By leveraging unique terpenes and key cannabis strains, growers, processors, and producers can differentiate themselves – and their products— in this ever growing market. Additionally, the potential medical benefits of terpenes are continually explored and new analysis opportunities surge.

Most cannabis concentrates are extracted using a solvent such as supercritical CO2, butane, hydrocarbon (hexane), propane, water (ethanol) or alcohol. These solvents are used to extract out the cannabinoids & terpenes from the plant material. In some cases, impurities from the solvent remain in the final cannabis product. These are called residual solvents and understanding their concentration is a critical element of cannabis testing.

A Simultaneous Turnkey Method

Whether you are focused on meeting stringent regulations or on maintaining strain consistency, the Clarus® SQ 8 GC/MS is unsurpassed in both sensitivity and stability. Coupled with the TurboMatrix headspace sampler and engineered to deliver unparalleled precision, sensitivity, and productivity, the Clarus GC/MS system is the clear choice for laboratories serving the cannabis market.

Concentrating on Residual Solvents

The method of choice for quantifying residual solvents is headspace gas chromatography, a simple technique that allows only the volatile component of the cannabis sample to be measured. Our preinstalled method for GC/MS with headspace technology leverages the identical instrumentation required for terpene analysis, allowing the streamlined lab to run both tests simultaneously.

Isolating and Analyzing Terpenes

Terpene analysis is run on a GC/MS with headspace capabilities. With easy sample preparation, this laboratory analysis can be used to look at over 140+ terpenes of varying concentrations. With easy sample preparation, this laboratory analysis takes no time away from production and can be included in residual solvent reports for client.
