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
A Review of the Latest Separation Science Research in PFAS Analysis
October 17th 2024This review aims to provide a summary of the most current analytical techniques and their applications in per- and polyfluoroalkyl substances (PFAS) research, contributing to the ongoing efforts to monitor and mitigate PFAS contamination.
Identifying PFAS in Soil Samples
October 17th 2024Jonathan Zweigle of the University Tübingen spoke with LCGC International about his work using non-targeted screening based on high-resolution mass spectrometry (HRMS) to detect PFAS in soil samples. HRMS allows scientists to determine the elemental and isotopic composition of a sample with high accuracy.
