Use of near infrared spectroscopy and chemometrics for the classification of different Cannabis spp. samples found in Belgium
hemp or cannabis flowers containing less than 0.2% m/m of Δ9- THC. Conclusion Near infrared spectroscopy allows to discriminate various samples. The difference is caused by the totality of compounds of ...
GEONs API fingerprint project: Selection of analytical techniques for clustering of sildenafil citrate API samples
14 different manufacturers were collected throughout the Network. Fingerprint data was collected through Mid-Infrared spectroscopy, Raman spectroscopy, liquid chromatography for related substances, gas ...

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.
2017 and 2018 two different unknown suspicious preparations were encountered and were subjected to a plethora of different analyses in order to identify, if present, any bioactive compound. It turned out ...
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 ...
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.
weight of less than 5kDa. Most of them are meant for subcutaneous injection and are easily accessible via the internet. In recent years, different methods based on reversed phase liquid chromatography have ...
A simple dilute and shoot methodology for the identification and quantification of illegal insulin
approach is not only able to distinguish between all those different versions of insulin and the insulins originating from different species, but also able to chromatographically separate human insulin and ...
