Multidimensional Chromatographic Fingerprinting Combined with Chemometrics for the Identification of Regulated Plants in Suspicious Plant Food Supplements.
the chromatogram, a multidimensional fingerprint (absorbance × wavelength × retention time) was considered. This was achieved by selecting several wavelengths through a correlation analysis. The data ...
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 ...
The occurrence of non-anatomical therapeutic chemical-international nonproprietary name molecules in suspected illegal or illegally traded health products in Europe: A retrospective and prospective study.
molecules of biological origin, that is, research peptides, representing the second most reported category in this study. Furthermore, the study also clearly shows the increasing popularity of Selective ...
Development and validation of chromatographic methods for screening and subsequent quantification of suspected illegal antimicrobial drugs encountered on the Belgian market.
agents, 1 antifungal agent and 1 beta-lactamase inhibitor, covering eleven different antibacterial classes, were selected. The UHPLC- MS screening method with gradient elution is able to selectively detect ...
Analysis of illegal peptide drugs via HILIC-DAD-MS.
five different HILIC columns were selected and screened for their chromatographic performance. Among those columns, the ZIC HILIC column showed the best performance under the tested screening conditions ...
A simple dilute and shoot methodology for the identification and quantification of illegal insulin
insulin lispro in conditions that are compatible with mass spectrometry (MS). Additionally, we were also able to selectively quantify the different insulins, including human insulin and insulin lispro ...
