Hi greatone100-ga,

  This page contains a nice description:

http://caag.state.ca.us/bfs/toxlab/gcms.htm

  The key part is:

Fragmentation is when ions in the GC or MS chamber fragment into
neutral species that are unmeasurable. More  fragmentation means less
precision in your measurement or an underestimation of mass in the
chamber.

  Does that make sense?
