Ultrafast ionization and fragmentation dynamics represent a pivotal frontier in modern chemical physics. Advances in femtosecond laser technology have enabled scientists to observe, in real time, the ...

Collision-activated dissociation (CAD), the most widely used peptide ion fragmentation technique for peptide sequence analysis by tandem mass spectrometry, works great for small peptides but is ...

This article outlines some of the commonly used mass spectrometers for proteomics. This includes several instrument ...

Ion-mobility spectrometry (IMS) separates and characterizes ions in the gas phase based on their mobility within a carrier gas. IMS has recently being coupled with mass spectrometry (MS) and ...
