Ionization Mode - EI Fixed
When AGC is off, a fixed ionization time scan function is used to coordinate the
processes that occur in the ion trap. This scan function consists by default of four
segments that compare qualitatively to those of the Auto scan function. It may
contain up to six segments. However, the fixed ionization time scan function
contains no prescan. Thus, the ionization times for each segment do not vary as
a function of sample concentration. The Ionization Time can be set from 10 to
65,000 µsec.
Manual tuning in Fixed mode is performed by altering the Ionization Storage
Levels and Ionization Times for each segment of the microscan.
