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

extracted with a multi-residue Quick Easy Cheap Effective Rugged Safe (QuEChERS) method and analyzed by a combination of gas and liquid chromatography tandem mass spectrometry (GC- MS / MS and LC- MS / MS) by ...

Towards the development of innovative multi-mycotoxin reference materials as promising metrological tool for emerging and regulated mycotoxin analyses.

Keywords: Animals Chromatography, Liquid Food Analysis Mycotoxins Reference Standards Tandem Mass Spectrometry Temperature Abstract: The interest in LC- MS / MS multi-mycotoxin methods unveiled an urgent need ...

An application of mass spectrometry for quality control of biologicals: Highly sensitive profiling of plasma residuals in human plasma-derived immunoglobulin.

information required. BIOLOGICAL SIGNIFICANCE: This study characterized residual plasma proteins in Ig products, using bottom-up LC- MS / MS with conventional data-dependent acquisition, preceded by sample fractionation. ...

Proof-of-concept study of a new LC-ESI-MS/MS-based assay to identify Aspergillus spp. in artificially mixed samples using species/genus-specific proteotypic peptides

developed assay which can resolve most of these MALDI- TOF MS limitations. This assay is based upon multiplex liquid chromatography electrospray ionization tandem mass spectrometry (LC- ESI- MS / MS) for the ...
