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 ...

Towards the use of ion mobility mass spectrometry derived collision cross section as a screening approach for unambiguous identification of targeted pesticides in food

Conclusions The screening approach proposed in this study is unconventional and based on large mass accuracy (20 ppm) and retention time windows (0.5 min) to capture, in a first step, a maximum of detected ...

Development and validation of chromatographic methods for screening and subsequent quantification of suspected illegal antimicrobial drugs encountered on the Belgian market

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, ...

Sensitivity of African swine fever virus (ASFV) to heat, alkalinity and peroxide treatment in presence or absence of porcine plasma.

without peroxide (P). Time (T) dependent inactivation was evaluated in presence or absence of porcine plasma. HAPT-treatment at H = 48 °C, A = pH 10.2 and P = 20.6 or 102.9 mM HO during 10 min (T) ...

Time-and-motion tool for the assessment of working time in tuberculosis laboratories: a multicentre study.

in h:min:s for Xpert® MTB / RIF, mycobacterial interspersed repetitive unit-variable number of tandem repeats genotyping, Ziehl-Neelsen staining and manual fluorescence microscopy were respectively ...

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, ...

Evaluation of 16 commercial antibody ELISAs for the detection of bovine viral diarrhea virus-specific antibodies in serum and milk using well-characterized sample panels.

a matrix, DS e was much lower for competitive (c) ELISA s (min. 45%, max. 65%) than for indirect (i) ELISA s (min. 85%, max. 100%), partly because of the lower detection of positive samples from vaccinated ...

Les infections liées aux soins et l’usage d’antimicrobiens en maison de repos et de soins en Belgique: Résultats de l'étude de prévalence ponctuelle HALT-3 (septembre-novembre 2016)

multirésistants et d’un protocole portant sur l’hygiène des mains. Le jour de l’étude, 4,5 % des résidents souffraient en moyenne d’une infection (min-max: 0,0 – 17,5 %) soit 705 résidents. La prévalence moyenne ...

Risk Assessment of Florists Exposed to Pesticide Residues through Handling of Flowers and Preparing Bouquets.

pairs of cotton gloves were worn during two consecutive half days while handling flowers and preparing bouquets (from min 2 h to max 3 h/day). The residual pesticide deposits on the glove samples were ...
