Multidimensional chromatographic fingerprinting combined with chemometrics for the identification of regulated plants in suspicious plant food supplements
explored: (a) binary modelling and (b) multiclass modelling. The correct classification rate % (ccr%) for cross validation, modelling and external test prediction were used to select the optimal model for ...
COMBINATION OF CHEMOMETRICS AND MULTIDIMENSIONAL FINGERPRINTING FOR DETECTION OF REGULATED PLANTS IN PLANT FOOD SUPPLEMENTS
square – discriminate analysis. A minimum of 86% correct classification rate for external test set validation (17 sample for binary dataset and 59 samples for multiclass dataset) was observed for all ...
Multidimensional Chromatographic Fingerprinting Combined with Chemometrics for the Identification of Regulated Plants in Suspicious Plant Food Supplements.
DA) through (a) binary modelling and (b) multiclass modelling. The correct classification rates (ccr%) by cross-validation, modelling, and external test set validation were satisfactory for both ...
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 ...
Use of near infrared spectroscopy and chemometrics for the classification of different Cannabis spp. samples found in Belgium
GC- FID for total-tetrahydrocannabinol detection and quantification with an officially validated method. The analysis of these products was performed by FT- NIR spectrometer (spectra were recorded in ...
The occurrence of putative cognitive enhancing research peptides in seized pharmaceutical preparations: An incentive for controlling agencies to prepare for future encounters of the kind.
recommendation paper of the General European Official Medicines Control Laboratory (OMCL) network on the interpretation of screening results for unknown peptides by mass spectrometry, was also validated in ...
Development and validation of chromatographic methods for screening and subsequent quantification of suspected illegal antimicrobial drugs encountered on the Belgian market.
validated. These methods could be used for routine analysis and enable a more in-depth characterization of SF-antimicrobials. According to their popularity as SF-antimicrobials, 31 antibiotics, 3 antibacterial ...
Analysis of illegal peptide drugs via HILIC-DAD-MS.
been developed to detect and quantify these peptides. The emerging of more polar peptides however requires the introduction of other separation techniques. Therefore, we set out to develop and validate ...
A simple dilute and shoot methodology for the identification and quantification of illegal insulin
according to the validation criteria, put forward by the United Nations (UN), for the analysis of seized illicit drugs. The proposed identification and quantification method is currently being used in our ...
