To clean the differential aperture:
1.
Place the differential aperture in the glass vessel.
2.
Add Waters MS Cleaning Solution or 1:1 methanol/water to the vessel until the differential
aperture is immersed completely.
3.
Place the vessel containing the differential aperture in the ultrasonic bath for 20 minutes.
4.
Carefully pour the cleaning solution from the vessel holding the differential aperture into the
holding container, retaining the differential aperture 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 differential aperture, and then discard the
water.
6.
Refill the vessel with deionized water, to rinse the differential aperture a second time, and
then discard the water.
7.
Fill the vessel with isopropyl alcohol, ensuring that the differential aperture is immersed
completely.
8.
Place the vessel containing the differential aperture in the ultrasonic bath for 20 minutes.
9.
Carefully remove the differential aperture from its vessel, and blow-dry the component using
inert, oil-free gas.
10. Discard the used isopropyl alcohol, using an appropriate waste container.
3.9.3
Cleaning the ion guide assembly
Required materials:
•
Chemical-resistant, powder-free gloves.
•
Suitable vessel in which to completely immerse the ion guide assembly when cleaning.
•
Two lengths of PEEK
,
PTFE, or stainless steel tubing, appropriately sized for suspending
the ion guide assembly in the glass vessels when cleaning.
•
HPLC-grade deionized water.
•
Waters
MS Cleaning Solution (186006846) or HPLC-grade (or better) 1:1 methanol/water.
•
Holding container for used Waters MS Cleaning Solution.
•
HPLC-grade isopropyl alcohol.
•
Ultrasonic bath.
•
Source of oil-free, inert gas (for example, nitrogen) for drying.
Warning:
To avoid personal contamination with biohazards or toxic materials, always wear
chemical-resistant, powder-free gloves while performing this procedure.
