Overview of Residual Solvents Analysis for Cannabis and Hemp

A brief look at the PerkinElmer QSight Pesticide Analyzer capabilities

QSight Pesticide Analyzer

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 and 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.
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-HS technology leverages the
identical instrumentation required for terpene analysis, allowing the
streamlined lab to run both tests simultaneously.

Solving Residual Solvent Analysis

High-performance liquid chromatography tandem mass spectrometry (LC-MS/MS) has emerged as the method of choice for pesticide and mycotoxin analysis in cannabis. Traditionally, pesticides are screened using two analytical instruments: GC-MS/MS and LC-MS/MS. However, most of the studies for the two system technology approach either do not achieve California State action-limits or require multiple time consuming sample preparation methods. Not so with PerkinElmer’s QSight 220 Pesticide Analyzer. Utilizing a single instrument and single prep method, our method is rapid and reliable— suitable for labs wanting to comply with stringent regulations. The recovery of all pesticides and mycotoxins from a cannabis matrix is consistently in the State of California’s acceptable range of 70-120% with RSD less than 20%. This method allows identification and quantification of all 66 pesticides and five mycotoxins at levels well below action limits (0.005 to 0.25 µg/g). The ability to screen and quantitate the hydrophobic and chlorinated compounds normally analyzed on a GC-MS/MS, as well as the five mycotoxins, makes this a novel technique for the cannabis industry. Highlights of the Turnkey Method for Pesticide and Mycotoxin Analysis: --Analysis of all California regulated pesticides and mycotoxins on a single LC-MS/MS --Eliminates the need for GC-MS/MS by using APCI source (APCI used for PCNB and Chlordane) --StayClean technology addresses matrix-induced maintenance issues in the MS instrument and improves throughput --A method with LOQs below state of California action limits that is reliable and reproducible --Simple and fast sample preparation procedure with acceptable recoveries for all analytes) --Dual source, ESI/APCI, removes need for two instrument platforms in a lab --Complete application includes analysis of mycotoxins and pesticides with one instrument (sample preparation, chromatography, and mass spectrometry)
