Multidimensional chromatographic fingerprinting combined with chemometrics for the identification of regulated plants in suspicious plant food supplements
× time points) were used for selection of orthogonal wavelengths by conducting a correlation analysis. After preparation of triturations, recording of the fingerprints and creation of datasets (corrected ...
COMBINATION OF CHEMOMETRICS AND MULTIDIMENSIONAL FINGERPRINTING FOR DETECTION OF REGULATED PLANTS IN PLANT FOOD SUPPLEMENTS
corrected for time shifts using correlation optimized warping and further pretreated using classical techniques like signal noise variate, autoscaling and derivatives), before being subjected to partial least ...
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.
the use of relative response (sometimes called relative correction factors) factors (RRF s) towards reference standards, different of the compound to be quantified, gained attraction. This study ...
Use of near infrared spectroscopy and chemometrics for the classification of different Cannabis spp. samples found in Belgium
Score plot of the PC1, PC2 and PC3 of spectra pretreated. Samples with >0.2% THC in red and blue and sample with < 0.2% THC in green. The SIMCA classification model has a correct classification rate ...
Characterization and risk identification of falsified medicines and adulterated dietary supplements
medicines is not enough to evaluate their risk and that a broader characterization of the products is necessary for a correct risk evaluation. In another part of the project an onsite infrared based approach ...
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.
that controlling laboratories need to anticipate the uprising of these types of potentially dangerous molecules and must therefore be able to correctly identify these compounds. Therefore, these findings ...
Comparative dissolution study on substandard and falsified antibiotics encountered in Belgium
parameters of drug quality control [2]. In this context, SF antimicrobials containing the correct dosage of claimed API s can exhibit poor dissolution performance. Thus, it is necessary and crucial to execute ...
