App Notes

A lab’s largest purchases is an LC–MS instrument. The lab needs an instrument tough enough for cannabis that has the sensitivity to meet the needs of ongoing changes in regulations.

The state of Massachusetts regulates nine pesticides at 10 ppb in flower. These strict action levels necessitate a highly sensitive mass spectrometer, such as the SCIEX 6500+ QTRAP® system.

UCT’s Selectra® C18 Column provides for a simple and robust method for the detection and quantitation of 16 cannabinoids in hemp and cannabis samples.

This application describes the analysis of arsenic, cadmium, mercury, and lead by ICP-MS in several varieties of hemp.

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

Isocratic HPLC method for the analysis of mycotoxins / aflatoxins.  Uses the DFL-10  filter fluorescence detector  with a photochemical reactor to improve sensitivity.

UCT’s Selectra® C18 Column provides for a simple and robust method for the detection and quantitation of 16 cannabinoids in hemp and cannabis samples.

In this application note, we present the sample preparations and experimental conditions for the analysis of Canadian cannabis pesticides. Method performance data is shown that demonstrates the successful analysis of the Canadian cannabis pesticides in a flower matrix.

In this application note, we present the most commonly observed errors and challenges when analyzing pesticides in cannabis products and suggestions on how to avoid or correct these issues.

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

Water is found in all cannabis products, and too little or too much can alter its properties. Controlling the moisture content will lead to a more reliable product.

To assist in optimizing for high throughput while maintaining sensitivity and resolution, this application demonstrates a sub-five-minute gradient method utilizing LC-MS/MS.

Cannabis is available in numerous forms, making the development of rugged, quantitatively accurate methods a challenge. This study optimizes a quantitative chromatographic determination of 15 cannabinoids using an HPLC analyzer.

An HPLC method for the testing of CBD oils. The DLC-10 is a small footprint, easy-to-use and low-cost HPLC system. An isocratic assay offers reliability and ease of use.

Potency testing and cannabinoid profiling are high-demand tests that can be improved by increasing speed, expanding analyte lists, and reducing costs.

UCT’s Selectra® C18 Column provides for a simple and robust method for the detection and quantitation of 16 cannabinoids in hemp and cannabis samples.

Cannabis flower must be filtered prior to HPLC or LCMS analysis. This note presents an evaluation of syringe filters used during the sample preparation process.

This isocratic LC-UV analysis of cannabinoids provides complete resolution of 16 cannabinoids, allowing accurate quantitative potency and profile data to be reported.

This application note demonstrates a simple way to test the CBD and THC in Cannabis Extraction industry by PERSEE HPLC with a simple configuration, isocratic pump and UV detector.

Patient and consumer safety is a critical factor during manufacturing of your products. In addition, false test results in product quality testing can lead to unnecessary scrapping of batches and product recalls. Good pipetting practices using filtered and pure pipette tips help ensure contamination-free pipetting to prevent contamination during sample preparation, ensuring true test results and patient and consumer safety

This application note outlines a QuEChERS extraction approach coupled with either traditional dSPE clean-up versus UCT’s dSPE clean-up in a 96 wellplate format.

Pre-made, multi-component CRM mixtures save time and consumable cost in the preparation of standard curves and improve quantitation accuracy.
