Because the collision cross section (CCS) of a protein is related to its overall shape, the measurement can provide information about various conformations the molecule adopts. A protein’s CCS, which ...

The study of ion–molecule collision dynamics and cross sections represents a cornerstone in understanding fundamental atomic and molecular interactions. This area of research combines both ...

Although ion mobility can separate ions very well, it still has some limitations. Since accurate experimental CCS determination in untargeted analysis usually requires reference CCS from standards.

Cross sections tell physicists how likely particles are to interact in a given way. Imagine two billiard balls rolling toward one another. The likelihood of a collision depends on easy-to-grasp ...
