App Notes

Accuracy in cannabis analytical testing starts with sampling & sample preparation prior to testing. The basis of accuracy is based on: representative samples & homogeneity.

Filtering winterized extract is a critical step in every extraction process. Done well, it can accelerate production. Done poorly, it can become a bottleneck.

With the different hemp and cannabis products on the market, all with various levels of cannabinoids, quality control to monitor the level of cannabinoids is crucial.

This application note demonstrates how CEM’s EDGE rapidly and automatically extracts various cannabis and hemp containing products in preparation for pesticide analysis.

This application note demonstrates rapid automated extraction and analysis of THC, THCA, CBN, CBA, and CBDA from hemp flower.

When your critical cannabis and hemp analyses are on the line, turn to the team at CEM for expert advise on how to achieve the results you need with systems that are accurate and easy to use.

This application note demonstrates analysis of terpenes extracted from cannabis standards using a novel GC-FID system.

Review the Official AOAC method for the determination of heavy metals in a variety of cannabis and cannabis products and learn tips and tricks for sample prep and analysis from the method authors.

Filtering winterized extract is a critical step in every extraction process. Selecting a pump that is reliable and offers the right vacuum levels can accelerate production.

Here, an effective workflow for this complex analysis was developed in brownies, and optimization strategies are detailed in order to provide a starting point for similar matrices.

This application note provides guidance on how to choose the right balance, when to calibrate your balance, how to weigh correctly, and how to care for your balance.

Streamlining the process of sample extraction in the lab can be achieved by reducing repetitive and time-consuming tasks with safe and convenient solutions for higher throughput.

This application note outlines an extraction method for four natural cannabinoids and the two major metabolites of Δ9-THC in blood using Clean Screen® THC SPE column.

Isolation of eight common cannabinoids for the determination of analytical cannabis content.

This application note provides guidance on how to choose the right balance, when to calibrate your balance, how to weigh correctly, and how to care for your balance.

Flavonoid profiling adds to the overall experience and profitability of full spectrum cannabis products.

This whitepaper outlines how new & existing processing labs can begin successfully making live rosin SKUs and how to use quality fresh frozen material to do so. 

By utilizing the Crystalline device coupled with a Tornado Raman spectrometer, it is possible to monitor and track polymorphism and morphology at low working volumes.

Automating your solid-state screening process enables you to perform the crystallization experiments with just a small amount of effort. Both CrystalBreeder and Crystal16 are the perfect tools for determining solubility in an easy and efficient manner. The solubility of your compound in organic solvents or water plays an important role when designing a crystallization screen. Knowing the solubility will allow you to select suitable solvents for the different crystallization methods.

The equipment used to achieve deep, stable vacuum, and separate fractions at the lowest possible temperature is critical to the process. Learn how using precise vacuum control allows for more efficient separation of plant oils and terpenes.

Finding the right combination of temperature and pressure allows the drying or evaporation process in a purge oven to be efficient. Learn how the vacuum pump used with a purge oven can maximize solvent recovery.
