In a commentary published in Environmental Health Perspectives, researchers voiced concerns about the limitations in PFAS research due to restricted access to high-purity reference standards.

Researchers investigating the relationship between cannabis use during pregnancy and depressive symptoms—and whether continued use beyond the first trimester or higher levels of use were linked to increased symptoms—used liquid chromatography–tandem mass spectrometry (LC–MS/MS) to confirm the presence of 11-nor-9-carboxy-delta-9-tetrahydrocannabinol (THC-COOH) in urine samples.

University of Valladolid scientists used a miniaturized method for analyzing biogenic volatile organic compounds (BVOCs) emitted by tree species, using headspace solid-phase microextraction coupled with gas chromatography and quadrupole time-of-flight mass spectrometry (HS-SPME-GC–QTOF-MS) has been developed.
