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 ...

Clustering of Tadalafil API Samples According to their Manufacturer in the Context of API Falsification Detection

solvent and 1 H- NMR data. Future suspicious samples in the network will therefore be analysed with these techniques in order to attribute the sample to one of the manufacturers. If the sample cannot be ...

From b to y ions, a decade of experience with peptide and protein analysis

recombinant expression technologies, and peptide synthesis have led to an increased development of protein and peptide therapeutics. Due to improved and simplified manufacturing techniques, disregard for patent ...

GEONs API fingerprint project: Selection of analytical techniques for clustering of sildenafil citrate API samples

future with the selected techniques in order to link the sample to a manufacturer or demonstrate the absence of such link. If the sample cannot be attributed to one of the manufacturers, further analysis ...

European fingerprint study on omeprazole drug substances using a multi analytical approach and chemometrics as a tool for the discrimination of manufacturing sources

analysis carried out by 7 European laboratories on 28 samples from 11 manufacturers with 5 analytical techniques (related substances with HPLC, residual solvents with GC- MS, near infrared spectroscopy, ...

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 ...

The development of a characterisation approach for Amphetamine, Cocaine and Ketamine samples, using infrared and Raman techniques

Falsification of biotechnology drugs: current dangers and/or future disasters?

electrophoretic techniques, immunological assays and mass spectrometry based approaches to merely identify the content of seized samples. In addition, the difference in size (peptide vs proteins vs monoclonal ...

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 ...
