Development and validation of chromatographic methods for screening and subsequent quantification of suspected illegal antimicrobial drugs encountered on the Belgian market.
”total error” approach in accordance with the validation requirements of ISO-17025 was employed for the validation. 57 real-life illegal samples, seized by inspectors from the Belgium Federal Agency for ...
Development and validation of chromatographic methods for screening and subsequent quantification of suspected illegal antimicrobial drugs encountered on the Belgian market
resulted in a validation set of 11 antimicrobials and 1 beta-lactamase inhibitor. The ”total error” approach in accordance with the validation requirements of ISO-17025 was employed for the validation. 57 ...
Detection and identification of multiple adulterants in plant food supplements using attenuated total reflectance—Infrared spectroscopy
Number 119 (2018) Keywords: ATR-(N)IR; Plant Food Supplements; Chemometrics; Mobile detection approaches Health Topics: Effectiveness and safety of vaccines, medicines and health products- Quality of ...
A new approach to define acceptance limits for hematology in external quality assessment schemes.
CONCLUSIONS: The approach enabled to determine state of the art-based AL s, that were concentration-dependent when necessary and usable by various EQA providers. It could also easily be applied to other domains. ...
Chemometrics and chromatographic fingerprints to classify plant food supplements according to the content of regulated plants.
objective way. Two approaches were followed: (1) a multiclass model, (2) 2-class model for each of the targeted plants separately. For both approaches good classification models were obtained, especially when ...
Detection of regulated herbs and plants in plant food supplements and traditional medicines using infrared spectroscopy.
compressed into tablets or capsules. The classical identification approaches based on micro- and macroscopy are therefore not possible anymore. In this paper infrared spectroscopy, combined with attenuated ...
Characterization of suspected dermal fillers containing hyaluronic acid
identity confirmation and quantification with the carbazole micro-assay. The method was successfully validated using the “total error” approach in accordance with the validation requirements of ISO-17025. ...
Development and validation of a HS/GC-MS method for the simultaneous analysis of diacetyl and acetylpropionyl in electronic cigarette refills
Number 224, p.218- 224 (2017) Keywords: Analyses analysi analysis approach AS Belgium bias Brussels Control Development electronic EVALUATION food health identify Institute IS journal measurement Medicine ...
Zona pellucida gene mRNA expression in human oocytes is related to oocyte maturity, zona inner layer retardance and fertilization competence.
in the ZP, in the current study, the polarized light microscopy (PLM) approach was combined with analysis of the expression of the genes encoding ZP1, 2, 3 and 4, both in the oocytes and in the ...
Chromatographic fingerprinting as a strategy to identify regulated plants in illegal herbal supplements.
is not a simple task since plants are often crushed and mixed with other plants, which complicates their identification by usage of classical approaches such as microscopy. The aim of this study was to ...
