Potential Obstacles in Chromatographic Analyses Distinguishing Marijuana from Hemp
LCGC International's April series for National Cannabis Awareness Month concludes with a discussion with Walter B. Wilson from the National Institute of Standard and Technology’s (NIST’s) Chemical Sciences Division regarding recent research his team conducted investigating chromatographic interferences that can potentially inflate the levels of Δ9-THC in Cannabis sativa plant samples, and possible solutions to avoid this problem.
Assessing Banned Menthol Characterizing Flavors in Cigarettes with GC–MS
The United Kingdom banned menthol as a characteristic flavor in cigarettes in May 2020. Researchers tested cigarettes sold in 2021–2022 for menthol and other characterizing flavors through sensory and chemical testing, using gas chromatography–mass spectrometry (GC–MS) in their research.
