PubMed: Comments on "discrepancies between validated GC-FID and UHPLC-DAD methods for the analysis of Δ-9-THC and CBD in dried hemp flowers"
Drug Test Anal. 2022 Nov 10. doi: 10.1002/dta.3400. Online ahead of print.
The original article described difference of total Δ9 -THC contents determined by gas chromatography with flame ionization detection (GC-FID) and high-performance liquid chromatography with ultraviolet detection (HPLC-UV). We presumed that this difference was mainly caused by peak overlapping of Δ9 -THC and presumptive cannabielsoin (CBE) isomer on the GC chromatogram.
