Frequency of Cleaning
The frequency of cleaning the components of the mass spectrometer depends on the types and
amounts of samples and solvents that are introduced into the instrument. In general, for a
given sample and ionization technique, the closer a mass spectrometer component is to the
source of the ions, the more rapidly it becomes dirty.
• Clean the sample transfer line, sample tube, and API probe at the end of each operating
day to remove any residual salts from buffered mobile phases or other contamination that
might accumulate during normal operation. See “Flushing the Sample Transfer Line,
Sample Tube, and API Probe” on page 66.
• Periodically remove and clean the ion transfer tube and ion sweep cone of the API source.
See “Maintaining the Ion Sweep Cone and Ion Transfer Tube” on page 79.
• 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) of the
Q00 ion optics become dirty at a slower rate than the API probe, ion sweep cone, and ion
transfer tube. See “Cleaning the S-Lens and Exit Lens (TSQ Vantage)” on page 87.
• The rf lens of the Q00 ion optics becomes dirty at a rate significantly slower than the
API source, tube lens and skimmer, or S-lens and exit lens. See “Cleaning the Q00 Ion
Optics” on page 91.

The frequency of cleaning the components of the mass spectrometer depends on the types and amounts of samples and solvents that are
introduced into the instrument. Cleaning of the Q0, Q1, Q2, and Q3 quadrupoles is rarely (if ever) required.
