Lipid Peroxidation in Algae Oil: Antagonist Effects of Natural Antioxidants

Molecules, 2022
Tandem mass spectrometry is proposed to check lipid oxidation, a free radical-mediated phenomenon which effects oxidative deterioration in polyunsaturated fatty acids. Antioxidants are used by the food industry to delay the oxidation process.

Quantification of sirolimus by liquid chromatography-tandem mass spectrometry using on-line solid-phase extraction [PDF]

, 2002
Quantification of the new immunosuppressant sirolimus (syn. rapamycin; Rapamune((R))) in whole blood by chromatography is essential for its clinical use since no immunoassay is available although monitoring is mandatory.

Estudo por espectrometria de massas de soluções de hidróxi(tosilóxi)iodobenzeno: propostas para mecanismos de desproporção

Química Nova, 2012
Solutions of [hydroxy(tosyloxy)iodo]benzene (HTIB or Koser's reagent) in acetonitrile were analyzed using high resolution electrospray ionization mass spectrometry (ESI-MS) and electrospray ionization tandem mass spectrometry (ESI-MS/MS) under different ...

Rearrangement of {α-P2W15} to {PW6} moieties during the assembly of transition-metal-linked polyoxometalate clusters [PDF]

, 2016
We report the formation of two polyoxotungstates of the general formula [M6(PW6O26)(α-P2W15O56)2(H2O)2]23− (M = CoII or MnII), which contain {PW6} fragments generated from the [P2W15O56]12− precursor, which demonstrates for the first time the ...

Mass recalibration for desorption electrospray ionization mass spectrometry imaging using endogenous reference ions

BMC Bioinformatics, 2022
Background Mass spectrometry imaging (MSI) data often consist of tens of thousands of mass spectra collected from a sample surface. During the time necessary to perform a single acquisition, it is likely that uncontrollable factors alter the validity of ...

Evaporation and Discharge Dynamics of Highly Charged Multicomponent Droplets Generated by Electrospray Ionization [PDF]

, 2010
We investigate the Rayleigh discharge and evaporation dynamics of highly charged two-component droplets consisting principally of methanol with 2-methoxyethanol, tert-butanol, or m-nitrobenzyl alcohol.
