Tuning the <strong>ISQ</strong><br />
Tuning will improve the performance <strong>of</strong> your <strong>ISQ</strong>. For optimum stability, you should start<br />
tuning after the lights on the front <strong>of</strong> the instrument are a solid green. These lights indicate<br />
that the instrument has reached vacuum and that it is at the last set temperature. If the system<br />
has been powered <strong>of</strong>f for a period <strong>of</strong> time (a cold system), it takes longer (up to 4 hours) for<br />
the <strong>ISQ</strong> components to reach vacuum and temperature. If you did not vent the <strong>ISQ</strong> (system is<br />
hot), it takes approximately 30 minutes for the <strong>ISQ</strong> components to reach vacuum and<br />
temperature.<br />
IMPORTANT Be sure to give the <strong>ISQ</strong> enough time to stabilize. Otherwise, you may see<br />
mass drift, mass spectral changes, or changes in the fragmentation <strong>of</strong> your data.<br />
