This section contains general maintenance procedures for the ion source. To determine how
often to clean or perform maintenance on the ion source, consider the following:
• Compounds tested
• Cleanliness of the samples and sample preparation techniques
• Amount of time an idle probe contains a sample
• Overall system run time
These factors can cause changes in ion source performance, indicating that maintenance is
required.
Make sure that the installed ion source is fully sealed to the mass spectrometer with no evidence
of gas leaks. Regularly inspect the ion source and its fittings for leaks. Clean the ion source
components regularly to keep the ion source in good working condition.
CAUTION: Potential System Damage. Use only the recommended cleaning methods and
materials to avoid damaging the equipment.
Required Materials
• 1/4 inch open-ended wrench
• Flat-bladed screwdriver
• LC-MS-grade methanol
• LC-MS-grade deionized water
• Safety glasses
• Breathing mask and filter
• Powder-free gloves, nitrile or neoprene recommended
• Lab coat
