Since my long and winding first year as manuscript editor of Mass Spectrometry
Letter (MSL) is almost done, I'd like to celebrate it with all MSL readers by having a quick break for the summary of MSL volume 5.
First of all, MSL has published three review papers in this volume and these
reviews cover lipidomics, steroid profiling, and proteomics. Especially, the review on applications of electrostatic repulsion-hydrophilic interaction chromatography
(ERLIC) to proteomics in this issue 4 is believed to be the first ERLIC review in a
scientific journal. Also, MSL has had additional 17 papers on various fields of
sciences such as proteomics, lipidomics, clinical chemistry, core mass spectrometry, pharmacokinetics, environmental science, food safety, forensics, microbiology, metabolomics, nuclear chemistry, and traditional oriental medicine. If you didn’'t have many chances to read these interesting papers yet, I recommend you not to skip this issue 4 composed of interesting applications of mass spectrometry to forensics, microbiology, and lipidomics as well as an exciting study on chemical ionization!
With closing MSL volume 5, I’'d like to express my sincere appreciation to Editor
in Chief, associated editors, and editorial board of MSL for their devotion to its
publication and to all MSL readers for their interests to MSL.
Happy new year
