Recent Advancements in the Characterization of D‐Amino Acid and Isoaspartate Post‐Translational Modifications

Mass Spectrometry Reviews, EarlyView.
ABSTRACT One of the great triumphs of mass spectrometry‐based peptide and protein characterization is the characterization of their modifications as most modifications have a characteristic mass shift. What happens when the modification does not change the mass of the peptide?

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).

Antithrombin: Deficiency, Diversity, and the Future of Diagnostics

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Our healthcare system provides reactive sick‐care, treating patients after symptoms have appeared by prescription of generic and often suboptimal therapy. This strategy brings along high costs and high pressure which is not sustainable.

Practical Applications of Secondary/Extractive Electrospray Ionization (SESI): A Versatile Tool for Real‐Time Chemical Analysis

Mass Spectrometry Reviews, EarlyView.
ABSTRACT In the 1980s, researchers discovered the remarkable ability of electrospray plumes to effectively ionize gas‐phase molecules via secondary ionization. Around 20 years later—coinciding with the ambient mass spectrometry revolution—secondary electrospray ionization (SESI) and extractive electrospray ionization (EESI) coupled to mass spectrometry

Analysis of Methylated Quaternary Ammonium Compounds Using Hydrophilic Interaction Liquid Chromatography Combined With Mass Spectrometry

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Liquid chromatography‐mass spectrometry (LC–MS) is a powerful technique for the detection and quantification of methylated quaternary ammonium compounds (mQACs), such as acylcarnitines and methylated amino‐acid‐derived (betainized) compounds, in biological matrices.
