App Notes

The Zebron™ ZB-624PLUS™ show excellent selectivity for both residual solvents and terpenes on one column for both light and heavy analytes.

The work presented here will describe the adjustments necessary to run flash columns on any typical prep HPLC system in order to gain this extra level of versatility.

The use of APCI instead of ESI has the advantages of improved ionization for traditionally non-ionizable pesticides and greater robustness against matrix and, particularly in negative mode, being more selective.

Discover a reliable and robust HPLC method to separate Δ10-THC and Δ6a,10a-THC isomers produced from Δ9-THC degradation using a chiral HPLC stationary phase.

Quantitative analysis of mycotoxins commonly involves extensive clean-up due to matrix complexity. A sensitive and rapid LC–MS/MS approach for analysis was developed.

A simple solvent extraction of course hemp flower, followed by efficient GC-MS analysis of 31 terpenes in under 17 min.

The cannabis extraction process typically involves solvents such as hexane or alcohols that may remain in the final product. A unique headspace SPME-GC–MS approach was developed.

Hemp is known to bioaccumulate heavy metals. Various homogenization and milling approaches were explored for analysis of the “Big 4” heavy metals in hemp varietals using ICP-MS.

An optimized HPLC-UV method with long column lifetimes and reproducible retention of acidic cannabinoids developed by SupraRnD, a cannabis testing lab located in Kelowna, BC, , Canada.

State-mandated pesticide testing lists for cannabis vary widely in regards to quantity and concentrations. The OR pesticide list was analyzed using LC-MS/MS and GC-MS/MS

In this work, we describe a complete workflow for the analysis of California pesticides, mycotoxins, and cannabinoids in gummies using a single extraction procedure.

Learn how to choose the right balance, when to calibrate your balance, how to weigh correctly, and how to care for your balance.

This app note features a solution for acidic cannabinoid retention shift issues – using the same column validated in the AOAC official method 2018.11 for cannabinoids.

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

In this study, Sartorius Optifit tips and Safetyspace™ Filter tips were tested not to leach compounds of interest for cannabis quality control such as arsenic, cadmium, mercury, lead, or pesticides.

States that have legalized cannabis use also have a zero-tolerance workplace drug policy that usually requires a urine test of known metabolites of THC.

Improve the accuracy of water content analysis in cannabis and hemp using Karl Fischer titration.

This application note demonstrates the CEM MARS 6 for microwave digestion of mixed cannabis and hemp containing products in a single run and elemental analysis of these products.

This application note demonstrates the CEM MARS 6 for microwave digestion of mixed cannabis and hemp containing products in a single run and elemental analysis of these products.

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.
