Goal-Oriented Extraction Processes

Mar 1, 2018

One of the key challenges when designing a cannabis processing plant is the overwhelming number of options available. Within a cannabis processing plant, decisions about unit operations will need to be made around preprocessing, extraction, and purification.

Pesticide and Mycotoxin Analysis: Mastering the Complexity of the Cannabis Matrix

Feb 28, 2018

The method described here allows for the simultaneous analysis of 47 pesticides and five mycotoxins in cannabis in one simple QuEChERS procedure. This simple method is designed for implementation in start-up laboratories and in established laboratories that wish to streamline their sample preparation process, decrease solvent usage, and obtain accurate and fast results.

Liquid Chromatography– Time-of-Flight Mass Spectrometry for Cannabinoid Profiling and Quantitation in Hemp Oil Extracts

Feb 28, 2018

A primary impediment to cannabinoid research is the fact that materials possessing psychoactive Δ9-tetrahydrocannabinol (THC) are considered Schedule I drugs as defined in the U.S. Controlled Substances Act. An alternative source of cannabinoids may be found in hemp oil extracts. Hemp contains a low percentage of THC by weight but relatively high amounts of nonpsychoactive cannabinoids. The liquid chromatography–time-of-flight mass spectrometry (LC–TOF-MS) method presented herein allows for the accurate, precise, and robust speciation, profiling, and quantification of cannabinoids in hemp oil extracts and commercial cannabinoid products for research and development laboratories. The method was determined to chromatographically separate 11 cannabinoids including differentiation of Δ8-tetrahdrocannabinol and THC with excellent linear dynamic range, specificity, and sensitivity.
