Sample introduction is one of the most critical steps in gas chromatographic analysis. In this webinar, we compare traditional headspace sampling with solid phase microextraction (SPME). The SPME-arrow technique is an optimization of the traditional SPME technique exploiting an increased adsorbent phase surface area. The increased sensitivity that is achieved by this technique allows identification and quantification of low abundant terpenes which in principle allows for better authenticity control of cannabis products by detecting compounds that are uniquely present in specific varieties. This technique also allows the use of much smaller sample volumes which is of interest when limited sample is available. In this webinar, the validated headspace and SPME-arrow techniques used in our laboratories are compared regarding their analytical precision, accuracy, reproducibility and LOQ.

Advantages and disadvantages of analytical strategies deployed for comprehensive terpene profiling in cannabis cultivars

Specificity merits of SPME adsorbents and time/temperature effects on sampling

How trace terpene analysis could be applied to verify/reject product authenticity

 Fungal contamination continues to be an issue for cannabis cultivation regardless of the mode of product (indoor grow facility or outdoor field). Recent studies have found that the rate for microbial failure can be as high as 10–20% of batches produced, with a majority of failures linked to fungal contamination. At the request of state regulators, AOAC INTERNATIONAL launched an Emergency Response Validation (ERV) program to rapidly certify candidate methods for enumerating yeast and molds in cannabis flower. Attendees of this webcast will gain insight into

State regulations for microbial contaminants, including total yeast and mold count

Validation results for candidate methods within the ERV program

Differences in state regulations for microbial contaminants

Editors’ Series: AOAC Emergency Response Validation for Total Yeast and Mold in Cannabis Products

 Hemp products (hemp flowers, seeds, seed oils etc.) are a group of very diverse and chemically complex raw materials that are used to produce many commercially available products. As part of their quality control and safety assessment, it is necessary to ensure that they are free from harmful levels of pesticides and chemical solvent residues. This analysis first requires the extraction and removal of many interfering compounds and separation into their constituent parts, followed by their quantification using a suitable analytical detector. In this presentation we describe a validated method for the analysis of approximately 600 pesticides in hemp products using GC/MS and LC/MS workflows.

Trends in Cannabis Extraction: Scaling Up and Purifying for Desired End Products

Accurate potency testing is a challenging task because hemp products take many forms, consisting of thousands of different compounds. Sample preparation is an important aspect of consideration to deliver accurate analyses. Typically, liquid chromatography with ultraviolet detection (LC-UV) is used for potency testing to ensure hemp product quality. Labs in an industrial setting need to implement this testing in the shortest time possible. In this webinar, Dr Marjeta Česen, Chief Regulatory Affairs Officer at Pharmahemp, will discuss how an in-house validated LC-UV potency method was used to benchmark a new commercially available potency-testing kit and associated workflow. The comparison of the methods used the same LC-UV systems to allow a like-for-like comparison.

From Post-Traumatic Stress to Post-Traumatic Growth:  How Medical Cannabis Is Helping Veterans with PTSD

https://www.cannabissciencetech.com/cst/thc_concentration

The focus on THC as a critical quality metric for cannabis producers is entirely predictable in jurisdictions legalizing cannabis around the world. The race to produce the highest THC cannabis flower happened in the legal US states and is currently happening in Canada. There is tremendous pressure to commercialize products with results showing high concentrations of THC which has created a moment of distrust between consumers and producers. In Canada a $500,000,000 class action lawsuit has been filed against top producers and shines a light on the labelling of cannabinoid concentration and the complexity of providing reliable data for cannabis products. As analytical labs navigate this complex problem, what tools do we have to ensure that we are reporting reliable results?

Understand how reliable analytical results for THC and CBD concentration is critical to ensure consistent product labelling and build industry confidence.

Identify tools and strategies that cannabis labs can utilize to overcome the complexity of the cannabis matrix to ensure they are reporting reliable results.

Discuss analytical interferences in cannabis and how can we improve the data quality.
