For “As needed” tasks, follow these guidelines:
• Clean the QJet ion guide and Q0 region if system sensitivity degrades.
• Clean the mass spectrometer surfaces after a spill, or when they become dirty.
• Empty the drain bottle before it becomes full.
Clean the Surfaces
Clean the external surfaces of the mass spectrometer after a spill or when they become dirty.
1. Wipe the external surfaces with a soft cloth dampened with warm, soapy water.
2. Wipe the external surfaces with a soft cloth moistened with water to remove any
soap residue.
Tip! Clean the Q0 region regularly to minimize the impact of charging (a
significant loss of sensitivity of the ions of interest over a short period of
time) on the quadrupoles and lenses. Contact a Qualified Maintenance
Person or AB SCIEX Field Service Employee (FSE).
