A simple dilute-and-shoot method for screening and simultaneous quantification of nicotine and alkaloid impurities in electronic cigarette refills (e-liquids) by UHPLC-DAD

and impurity levels, the majority of them use a targeted LC- MS / MS approach. There is, however, a need for more robust quantification methods that are easy to implement in most control (industrial and ...

Profiling of the beneficial and potentially harmful components of Trichodesma indicum seed and seed oil obtained by ultrasound-assisted extraction

LC-Q- TOF- MS. Rosmarinic acid (67%) and isomers of salvianolic acid B/E/L (26%) were the main phenolics, while melitric acid A and sebestenoid C/D constituted 6% and 1%, respectively. Only a minor part ...

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 ...
