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

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
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 ...
