A novel GC-MS/MS assay for the measurement of 2-hg enantiomers and the utility of 2-hg enantiomer levels as a biomarker for IDH mutant gliomas
… R-2-hg as a biomarker. Furthermore, the current mass spectrometry (MS) methods available for the separation and detection are lacking. Current assays use laborious methods that can result in interconversion of enantiomers during sample preparation, and since low-resolution mass spectrometry …

Structural elucidation of glycerophospholipids using metastable atom-activated dissociation mass spectrometry (MAD-MS)
… are analyzed through hyphenated chromatography-mass spectrometry instruments and especially using collision-induced dissociation (CID). Low-energy CID typically produces both headgroup and complete fatty acid chain loss, whereas high energy CID causes extensive fatty acid chain fragmentation. …

Trends and inferred emissions of atmospheric high molecular weight perfluorocarbons
… cryogenic preconcentration gas chromatography-mass spectrometry instruments, which are part of the Advanced Global Atmospheric Gases Experiment (AGAGE). A new calibration scale was prepared for each PFC, with estimated accuracies of 6.8% for C4Fi0 , 7.8% for C5F12 , 4.0% for CF 14 , 6.6% for …

Measurement of lipid peroxidation in biology models using gas-chromatography-aass spectrometry
… into a gas chromatograph with time-of-flight mass spectral capabilities (GC-TOFMS) and were found to include the lipid peroxidation product hexanal. The pro-oxidant cumene hydroperoxide elevated the levels of these lipid peroxidation products, whereas the anti-oxidant butylated hydroxy toluene …
