• Suitable holding container for storing the used cleaning solution
• Oil-free nitrogen gas or other oil-free, inert gas suitable for drying
Warning:
To avoid personal contamination with biologically hazardous, toxic, or corrosive
materials, and to avoid spreading contamination to uncontaminated surfaces, wear clean,
chemical-resistant, powder-free gloves when performing this procedure.
To clean the ion guide assembly:
1. Bend the PEEK or PTFE tube end into a hook shape.
2. Insert the hook into one of the holes in the ion guide’s rear circuit board carrier.
Important:
To avoid vibration-caused damage to the ion guide assembly, ensure that the
bottom of the assembly is not in contact with the bottom of the glass vessel.
3. Bend the opposite end of the tube into a hook shape that allows you to suspend the ion
guide assembly in the glass vessel so the bottom of the assembly does not touch the
bottom of the vessel.

4. Add Waters MS Cleaning Solution or 1:1 methanol/water to the cleaning glass vessel until
the ion guide assembly is immersed completely.
