Multidimensional chromatographic fingerprinting combined with chemometrics for the identification of regulated plants in suspicious plant food supplements
for shifts in retention times using correlation optimized warping), partial least squares – discriminant analysis was applied to construct classification models. Two approaches for modelling were ...
COMBINATION OF CHEMOMETRICS AND MULTIDIMENSIONAL FINGERPRINTING FOR DETECTION OF REGULATED PLANTS IN PLANT FOOD SUPPLEMENTS
fingerprints by performing a correlation analysis on the DAD data. Chemometric analysis was carried out using two approaches: 1. binary models for each plant separately and 2. multiclass models. The data were ...
Multidimensional Chromatographic Fingerprinting Combined with Chemometrics for the Identification of Regulated Plants in Suspicious Plant Food Supplements.
were recorded using ultra-high-performance liquid chromatography (UHPLC) coupled with diode array detection (DAD). Chemometric modelling was performed by partial least squares-discriminant analysis (PLS- ...
Multidimensional Fingerprint Development for the Detection of Tribulus terrestris in Plant Food Supplements
multidimensional data and extract maximum information with the intention to create binary models for faster screening of plant food supplements. Health Topics: Médicaments illégaux Illegal medicines Illegale ...
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.
performed a comparison of the use of RRF s and linear relative response factor models (LRRFM) for the quantification of targeted low-dosed compounds using an alternative standard, since it is known that ...
Use of near infrared spectroscopy and chemometrics for the classification of different Cannabis spp. samples found in Belgium
analysis (PCA) is applied as exploratory data analysis. Soft independent modelling of class analogy (SIMCA) was used to build a binary classification model according to the Belgian legislation. All ...
A strategy based on fingerprinting and chemometrics for the detection of regulated plants in plant food supplements from the Belgian market: two case studies
techniques in order to obtain classification models. A first classification model is calculated based on the infrared data and gives a first idea about the plant suspected to be present. This suspicion is then ...
