To clean the ion guide assembly:
1. Bend a PEEK, PTFE, or stainless steel tube into a hook shape and use to carefully suspend
the first ion guide PCB assembly in the glass vessel so that the bottom of the assembly
does not touch the bottom of the vessel.

2. Add Waters MS Cleaning Solution or 1:1 methanol/water to the glass vessel until the ion
guide is immersed completely.
3. Place the vessel containing the ion guide in the ultrasonic bath for 20 minutes.
4. Carefully pour the cleaning solution from the vessel holding the ion guide into the holding
container, retaining the ion guide in the vessel.
Tip: You can reuse Waters MS Cleaning Solution for one subsequent cleaning.
5. Fill the vessel with deionized water, to rinse the ion guide, and then discard the water.
6. Refill the vessel with deionized water, to rinse the ion guide a second time, and then discard
the water.
7. Fill the vessel with isopropyl alcohol, ensuring that the ion guide is immersed completely.
8. Place the vessel containing the ion guide in the ultrasonic bath for 20 minutes.
9. Carefully remove the ion guide from its vessel, and blow-dry the component using inert,
oil-free gas.
10. Discard the used isopropyl alcohol, using an appropriate waste container.
Notice: To avoid damage to the ion guide caused by vibration, ensure that the
bottom of the ion guide does not touch the bottom of the glass vessel.
