DRAFT DEFINITION
Low energy collision

Low-energy collisions are typical in the 1-1000 eV range and occur in quadrupoles, ion traps and hybrid instruments. The ion excitation is mainly vibrational and the choice of the collision gas is much more important than for high-energy collisions. For low energy collisions heavier gases are preferred since the energy transfer is greater which in turn leads to more fragmentation.

Considered between 2004 and 2006 but not included in the 2006 PAC submission
This is an unofficial draft definition presented for information and comment.
