6.3.8 MS Method Development
The MS->METHOD DEVELOPMENT menu command opens
the PurIon mass spectrometer method development window
(PurIon equipped systems only). This enables a user to test
and verify ionization conditions for their compound. This
command is not available from a remote connection.
This window contains the following controls:
• POLARITY—On the PurIon system, this control
changes the probe polarity between positive and
negative ionization. On PURION S and PURION L
systems, this button toggles the displayed mass
spectrum between positive and negative ionization.
• ION SETTINGS – Allows selection of different ion
settings to maximize the intensity of the desired
molecular ion. The factory selections include "Robust",
for compounds that do not easily ionize. "Typical" works
well for most compounds. The "Fragile" setting is used
for those compounds that are delicate or easily fragment.
User defined ion settings may also be loaded (see section
6.2.3.3)
• ION FINDER - Identifies potential adducts and
fragments for the compound of interest when the
compound of interest does not show up in the spectrum
graph.
