Multidimensional Chromatographic Fingerprinting Combined with Chemometrics for the Identification of Regulated Plants in Suspicious Plant Food Supplements.
the approach not so straightforward. This paper aims to tackle this problem by developing a multidimensional chromatographic fingerprinting method aided by chemometrics. To render more specificity to ...
CHROMATOGRAPHIC FINGERPRINT DEVELOPMENT FOR THE DETECTION OF TRIBULUS TERRESTRIS IN PLANT FOOD SUPPLEMENTS
Liquid Chro-matography- Diode-Array detector (UHPLC – DAD) and evaluated the presence of TT in 20 unknown illegal plant food supplements by using the developed fingerprinting method. Method: UHPLC- DAD was ...
Relative response factors and multiple regression models in liquid chromatography to quantify low-dosed components using alternative standards-proof of concept: total Δ9-THC content in cannabis flowers using CBD as reference.
was used as a case study. A chromatographic method was implemented and validated, and the use of classical calibration lines, classical RRF, and the LRRFM was applied and compared, with special focus on ...
