g. Set Ion Source Temperature —Select this check box to enable the temperature field.
Then enter a value between 0 and 350 °C. The default is 200 °C. The optimal
temperature is determined by the molecular structure and weight of the compounds
you are analyzing. Heavier compounds require a higher temperature. Tune at the
same temperature you will use to run your samples. You should set the temperature as
high as possible to keep the ion source clean and maintain the right amount of
sensitivity.
5. Click the Targets tab to configure how you want to tune your targets. Target tuning is
used to adjust the way the mass spectrometer tunes to meet regulatory requirements.
Otherwise, this is an optional setting.

Tune Target Ion Ratios —Select this check box to adjust the ratios based on the results
from an injection of tuning compound.
6. Click the Detector tab to configure the detectors. See Figure 99 .
Tip If you tune regularly between running sample sets, you can save time waiting
for the temperatures to equilibrate by setting the tune temperatures to the same
temperature used in your acquisition method.
