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.
Right From the Grow: A Look at Sampling and Sample Preparation Methods of Solid Cannabis for Analysis
Laboratories are challenged with highly regulated and difficult sample schematics, sample preparation, extraction, and testing procedures that try to ensure accuracy and precision of testing. Accuracy in analytical testing starts at the very beginning with sampling and sample preparation prior to testing.
Too often, cannabis laboratories get different results on the same sample. There are a number of causes and solutions. In this installment, the problem is presented along with its causes.
Learn why your sample needs to be stable, homogeneous, and representative of the batch from which it is taken.
Precise measurements are vital to any transaction of commerce.
Well-established techniques used by the food safety industry, such as QuEChERS sample preparation followed by LC–MS/MS for the analysis of multiresidue pesticides, are evaluated for use with cannabis plant material.
An interview with Jeff Dahl, an applications scientist at Shimadzu Scientific Instruments; Joe Konschnik, a business development manager for the food and beverage market at Restek Corporation; Andre Santos, the Americas market development manager at Agilent Technologies; Alicia D. Stell, the CEM product development lab manager; and Xiaoyan Wang, a research scientist at UCT
QuEChERS is introduced to the discipline of forensic testing as a viable method for the extraction of pesticides and cannabinoids in various complex sample matrices
The Benefits of ICP-MS for the Determination of Toxic and Nutritional Elements in the Cannabis Family of Flowering Plants
The wide dynamic range of ICP-MS allows it to be used for the simultaneous determination of parts-per-billion levels of heavy metals including lead, arsenic, cadmium, and mercury, together with high parts-per-million levels of nutritional elements, such as phosphorus, calcium, potassium, and magnesium.
Giuseppe Cannazza and Cinzia Citti from the University of Modena and Reggio Emilia discuss the growing interest in the use of medicinal cannabis in Europe and the analytical challenges involved.
