Determination and identification of acrylamide residues in poly-acrylamide by ultra-performance liquid chromatography-quadrupole electrostatic field orbitrap high-resolution mass spectrometry
Abstract:A new method for the direct determination of acrylamide residues in poly-acrylamide (PAM) by ultra-performance liquid chromatography (UPLC)-quadrupole electrostatic field orbitrap high-resolution mass spectrometry with the Hypercarb column was developed. With being diluted by water, the PAM sample was dissolved well by high-speed stirring. After filtering through a 0.22 μm aqueous phase microporous membrane, the sample was analyzed by high-resolution mass spectrometry directly. Chromatographic analysis was car… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
