Challenges in Drug Surveillance: Strengthening the Analysis of New Psychoactive Substances by Harmonizing Drug Checking Services in Proficiency Testing.
chromatography-mass spectrometry (GC- MS) and liquid chromatography with diode array detector (LC- DAD). RESULTS: The proficiency test scores range from 80 to 97.5% accuracy. The most common issues and errors are ...
Identification of Mycobacterium abscessus Subspecies by MALDI-TOF Mass Spectrometry and Machine Learning.
differentiation. Although matrix-assisted laser desorption/ionization-time of flight mass spectrometry (MALDI- TOF MS) has proven useful for NTM identification, the differentiation of M. abscessus subspecies is ...
Simultaneous Detection and Quantification of Aflatoxin M1, Eight Microcystin Congeners and Nodularin in Dairy Milk by LC-MS/MS
and sensitive LC- MS / MS method was developed and validated for the quantification of multiple cyanotoxins (microcystin congeners and nodularin) and AFM1 by the main analytical guidelines. Toxins are ...
Application of silver-based biocides in face masks intended for general use requires regulatory control
study optimized methodologies to characterize silver-based biocides directly in the face masks, by measuring their total silver content using ICP- MS and ICP- OES based methods, and by visualizing the ...
The contribution of cacao consumption to the bioaccessible dietary cadmium exposure in the Belgian population
the Belgian population, in combination with ICP- MS analysis of a large subset of cacao-containing products (N=349). Both the average chocolate consumption (28 g day-1) and the relative contribution of ...
Microbiological safety of aged meat.
prevented by ensuring a meat surface temperature of-0.5 to 3.0°C, with a relative humidity (RH) of 75-85% and an airflow of 0.2-0.5 m/s for up to 35 days. The main meat spoilage bacteria include spp, spp. ...
Evaluation of a Liquid Media MALDI-TOF MS Protocol for the Identification of Dermatophytes Isolated from Infections.
Matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI- TOF MS) is gaining new ground for routine identification of filamentous fungi. The main advantages of MALDI- TOF MS are its rapid ...
High diversity of yeast species and strains responsible for vulvovaginal candidiasis in South-East Gabon.
