The Cannabis Analytical Conundrum
Recently several states have legalized recreational and medical marijuana. This has created a confusing set of circumstances due to legalization at the state level, but cannabis is still an illegal schedule 1 drug at the federal level. This confusion also affects the development of analytical methods because there are no clear guidelines available to laboratories. This whitepaper will discuss the following topics: • Overview of state analytical requirements • Discussion of analytical method development for cannabinoids and related compounds of interest • Discussion of method performance
Measuring Vitamin K1 Concentrations in Dogs with Chronic Enteropathy Using LC–MS/MS
May 14th 2025A joint study between the University of Tennessee (Knoxville, Tennessee) and the University of Pennsylvania School of Veterinary Medicine (Philadelphia, Pennsylvania) compared directly measured vitamin K1 (vitK1) concentrations in healthy dogs and dogs with chronic enteropathy (CE) using liquid chromatography tandem mass spectrometry (LC–MS/MS); they also investigated whether supplementation of vitK1 in dogs with CE would significantly increase vitK1 concentrations.
