LC-MS

A deeper look into the chemistry, physics, and methodology of HPLC methods.

From simple separations to detailed wavelength analysis, we examine the important concepts and techniques needed to make liquid chromatography work its best in the laboratory.

A rapid LC–MS/MS method is presented for the quantitative analysis of 16 cannabinoids in hemp samples with a single dilution protocol.

A study using LC-qTOF, GCqTOF, and GC–MS/MS to evaluate the selectivity of a model pesticide commonly found in regulatory target lists.

Better, accurate and more reliable analytical testing is needed in the industry. The author discusses one such method that goes well beyond the current contaminant testing done today in most laboratories.

Some hemp-based products are mislabeled regarding their level of CBD. The authors explain why and how that happens.
