Collision cross-section determination of isomeric carotenoids using electrospray ion mobility time-of-flight mass spectrometry
Introduction Carotenoids are naturally occurring pigments that function as provitamin A compounds and antioxidants. Biosynthesized in plants as the all-trans isomers, carotenoids undergo isomerization to form multiple cis isomers which have been reported to have different bioavailabilities [1]. Although C30 stationary phases are available to facilitate the chromatographic separation of caroteno...

متن کاملTuning of an electrospray ionization source for maximum peptide-ion transmission into a mass spectrometer.
We describe assembly and optimization of a continuous flow nanoelectrospray source for high-performance analysis on a routine basis. It is derived from an inJection adaptable Fine Ionization Source ("JaFIS"), previously shown to be durable and easy to use (Geromanos, S.; et al. Rapid Commun. Mass Spectrom. 1998, 12, 551-556) and now modified for maximum sensitivity. Proper design, manufacturing...
متن کاملElectrospray Ionization Ion Mobility Mass Spectrometry of Human Brain Gangliosides.
The progress of ion mobility spectrometry (IMS), together with its association to mass spectrometry (MS), opened new directions for the identification of various metabolites in complex biological matrices. However, glycolipidomics of the human brain by IMS MS represents an area untouched up to now, because of the difficulties encountered in brain sampling, analyte extraction, and IMS MS method ...
متن کاملCollision cross section calibrants for negative ion mode traveling wave ion mobility-mass spectrometry.
Unlike traditional drift-tube ion mobility-mass spectrometry, traveling-wave ion mobility-mass spectrometry typically requires calibration in order to generate collision cross section (CCS) values. Although this has received a significant amount of attention for positive-ion mode analysis, little attention has been paid for CCS calibration in negative ion mode. Here, we provide drift-tube CCS v...
