78 TSQ Series Hardware Manual Thermo Scientific
When the performance of your system decreases significantly due to contamination, clean the
components of the mass spectrometer in the following order:
1. Clean the API probe, ion sweep cone, and ion transfer tube.
2. Clean the S-lens and exit lens (on the TSQ Vantage) or the tube lens and skimmer (on the
TSQ Quantum Access, TSQ Quantum Access MAX, and TSQ Quantum Ultra).
3. Clean the Q00 rf lens and lens L0.
Generally, do not open the vacuum manifold. Cleaning the Q0, Q1, Q2, and Q3
quadrupoles is rarely (if ever) required. (Q0 can be removed and cleaned along with Q00.) If
you believe that the Q1, Q2, or Q3 quadrupoles need cleaning, contact Thermo Fisher
Scientific and schedule a visit by a Thermo Fisher Scientific service engineer.
If you open the vacuum manifold, clean the electron multiplier and conversion dynode by
blowing them with a clean, dry gas. If you do not open the vacuum manifold, the electron
multiplier and conversion dynode do not normally require cleaning, although rarely the
electron multiplier might require replacement.
CAUTION As with all chemicals, store and handle solvents and reagents according to
standard safety procedures. Dispose of them according to local and federal regulations.
