Several different HPLC method options are explored for the efficient and time effective analysis of cannabinoids in a sample of hemp flower. The differences between gradient and isocratic analyses are explored, and the two methods are compared in determining the
A comprehensive high performance liquid chromatography-diode array detection (HPLC-DAD) workflow for the analysis of 14 cannabinoids in hemp bud extracts within 10 minutes using robust Chromolith® monolithic silica HPLC columns with low column back pressure.
High-performance liquid chromatography (HPLC) separation and quantitation of vitamin E acetate in commercially available vape products, in addition to simultaneous analysis of THC and CBD in the same run.
We offer a portfolio of cannabinoid CRMs such as THC and THCA, available as single component solutions or mixes, certified in accordance with ISO 17034 and ISO/IEC 17025 for accurate cannabinoid profiling and potency testing.
An overview of gradient HPLC-based analysis of cannabinoids, optimized for key method parameters such as column temperature, mobile phase pH, and methanol as low-cost organic modifier. Learn more here.
Development and validation of a LC-MS/MS method to determine concentration of cannabidiol (CBD) in human plasma samples with a shorter run time and no interference by two major metabolites of CBD; 7-carboxy cannabidiol and 7-hydroxy cannabidiol.
Analysis of heavy metals and metals in cannabis and hemp containing personal care products and cosmetics include sample preparation by grinding, preparation of calibration solutions for a standard addition approach, a microwave digestion protocol and subsequent ICP-MS analysis.
