14.1 Introduction to AutoTune and Manual Tune
The tune of a Mass Spectrometer (MS) determines the quality of the mass spectrum
produced by the system. The MS performance will run an autotune upon start-up and
after 12 hours of continuous operation. Tuning is normally accomplished by the
AutoTune program, which automatically sets and adjust all parameters, however, the
user can set the parameters by manual tuning.
HAPSITE ER uses two gas internal standards which contain mass fragments that
span the mass range of interest. The internal standards are:
• 1,3,5-Tris (trifluoromethyl) benzene
• Bromopentafluorobenzene
