Development and validation of chromatographic methods for screening and subsequent quantification of suspected illegal antimicrobial drugs encountered on the Belgian market.
these 36 compounds within 18 min (including wash and equilibration step). It was validated for sensitivity, selectivity and matrix effects. Within an analysis time of 32 min, the UHPLC- DAD method could ...

selected. The UHPLC- MS2 screening method with gradient elution is able to selectively detect these 36 compounds within 18 min (including wash and equilibration step). It was validated for sensitivity, ...
Analysis of illegal peptide drugs via HILIC-DAD-MS.
most frequently encountered illegal peptides on the internet in a total run time of 35min including post gradient equilibration and online cleaning step. Combined with a previously developed RPLC-method, ...
Ontwikkeling van een HILIC-PDA methode voor de detectie van illegale polypeptiden
ZIC ®- HILIC en ZIC ®-cHILIC kolom). Dit gebeurde bij drie temperaturen (30°C, 40°C, 50°C) en vier elutiesnelheden (0,2 ml/min, 0,3 ml/min, 0,4 ml/min, 0,5 ml/min). Als mobiele fasen werden een 10 mM ...
Analysis of illegal peptide biopharmaceuticals frequently encountered by controlling agencies.
diode array detection (UHPLC- DAD). The screening method, taking only 30 min, is able to selectively detect 25 different peptides and incorporates the proposed minimum of five identification points (IP) ...
Development and validation of a fast chromatographic method for screening and quantification of legal and illegal skin whitening agents.
latter having restrictions with respect to concentration and application (kojic acid, arbutin, nicotinamide and salicylic acid), but can also quantify these in a run time of 12 min. The method was ...
A validated GC-MS method for the determination and quantification of residual solvents in counterfeit tablets and capsules.
USA) with an oven temperature program from 60 °C (held for 5 min) to 270 °C at 25 °C/min. 270 °C is held for 10 min. The total run time is 23.4 min. The obtained method was fully validated by applying ...
Development and validation of a ultra-high-performance liquid chromatography-UV method for the detection and quantification of erectile dysfunction drugs and some of their analogues found in counterfeit medicines.
a gradient using acetonitrile as organic modifier and 10mM ammonium formate buffer (pH 3.5) as aqueous component of the mobile phase. The separation was achieved in less than 4.5 min. The method has also been ...
