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.
served as an incentive to develop a novel combined liquid chromatography tandem mass spectroscopy (LC- MS / MS) methodology, applicable to both hydrophilic or more hydrophobic peptides, which was utilized ...
Development and validation of chromatographic methods for screening and subsequent quantification of suspected illegal antimicrobial drugs encountered on the Belgian market.
validated. These methods could be used for routine analysis and enable a more in-depth characterization of SF-antimicrobials. According to their popularity as SF-antimicrobials, 31 antibiotics, 3 antibacterial ...
Impurity profiling of the most frequently encountered falsified polypeptide drugs on the Belgian market
drugs. Subsequent speciation of As confirmed the elevated concentrations for As and demonstrated that all As was present in the more toxic inorganic form. Together with the (sometimes) high amount of ...
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 ...
