Determination of Organophosphate Esters in Water Samples Using Gas Chromatography–Mass Spectrometry (GC–MS) and Magnetic Solid-Phase Extraction (SPE) Based on Multi-Walled Carbon Nanotubes (MWCNTs)
A GC–MS method, coupled with magnetic SPE with multi-walled carbon-nanotube (MWCNT)-coated iron oxide as the adsorbent, was developed for analyzing organophosphate esters in environmental water samples.
New Aspects in the Integration of MS Technologies in the Biopharmaceutical Industry
High-resolution mass spectrometry (HRMS) is an increasingly critical tool for identifying, characterizing, and monitoring attributes of protein-based therapeutics.
Determination of Organophosphate Esters in Water Samples Using Gas Chromatography– Mass Spectrometry and Magnetic Solid-Phase Extraction Based on Multi-Walled Carbon Nanotubes
A method based on GC–MS coupled with magnetic SPE with multi-walled carbon-nanotube-coated Fe3O4 as adsorbent was developed for the analysis of four organophosphate esters (OPEs) in ambient water samples. The method was validated for its comparable sensitivity and potential application prospect.
New Aspects in the Integration of Mass Spectrometry Technologies in the Biopharmaceutical Industry
Recent developments in high-resolution mass spectrometry (HRMS) are aiding biopharmaceutical development and simplifying routine monitoring, with applications in areas like multi-attribute methods, coupling established purity methods with MS, and subunit analysis.
