Cold EI—The Way to Improve GC‐MS and Increase Its Range of Applications

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Gas chromatography‐mass spectrometry (GC‐MS) with Cold electron ionization (EI) is based on interfacing the GC and MS with a supersonic molecular beam (SMB) along with electron ionization of vibrationally cold sample compounds in the SMB in a contact‐free fly‐through ion source (hence the name Cold EI).

Spatially Resolved 13C NMR Spectroscopy in Bimesophasic Samples Applied to Molecular Analysis in Orienting Media

Magnetic Resonance in Chemistry, EarlyView.
This paper presents a promising analytical tool for the extraction of anisotropic 13C information (RDC and RCSA) from two oriented but immiscible lyotropic chiral domains in a single NMR sample. The methodology is based on spatially resolved 13C 1D/2D NMR experiments using the OVS approach. ABSTRACT The use of lyotropic, chiral bimesophasic systems and

TE optimization for J‐difference editing of 2‐hydroxyglutarate at 3T

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose To investigate the TE dependence of the edited 2‐hydroxyglutarate (2HG) signal, its separation from co‐edited glutamate plus glutamine (Glx), and fit accuracy in the presence of nuisance signals using a MEGA‐PRESS sequence. Methods Simulations were performed at TEs 70–160 ms to assess the signal intensity and 2HG‐Glx overlap as a ...

Initial experience of cardiac T1ρ mapping at 0.55 T: Continuous wave versus adiabatic spin‐lock preparation pulses

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose To propose and validate a cardiac T1ρ mapping sequence at 0.55 T comparing continuous‐wave and adiabatic spin‐lock (SL) preparation pulses. Methods The proposed 2D sequence acquires four single‐shot balanced SSFP readout images with differing contrasts in a single breath‐hold.
