Maintaining the API Source Housing
Only Thermo Fisher Scientific service engineers can service the API source housing, while
user maintenance is limited to cleaning the housing as necessary. Follow all safety precautions
in the Ion Max NG and EASY-Max NG Ion Sources User Guide regarding the installation and
removal of the API source. For any additional service, contact your local Thermo Fisher
Scientific service engineer.
To clean the API source housing
1. After the API source cools to room temperature, remove it from the mass spectrometer.
2. Put on appropriate eye-wear and gloves.
3. In an appropriate fume hood, rinse the interior of the housing with LC/MS-grade
methanol.
4. Allow the housing to dry before you install it on the mass spectrometer.
