• Length of small diameter PEEK or Teflon
®
tubing appropriately sized
for suspending the hexapole in the glass vessel when cleaning.
• HPLC-grade (or better) methanol.
• Ultrasonic bath.
• Source of oil-free, inert gas (for example, nitrogen) for drying (air-drying

• Large beaker.
• Small, flat-blade screwdriver.
To clean the source hexapole assembly:
1. Bend the PEEK or Teflon tubing into a hook shape.
2. Insert one end of the hook into one of the holes on the hexapole
assembly’s rear support ring.
Warning:
The source hexapole assembly can be contaminated with
biohazardous and/or toxic materials. Always wear
chemical-resistant, powder-free gloves while performing this
procedure.
Caution:
To avoid damaging the StepWave assembly, do not use
acetone, chlorinated solvents, or acid as cleaning solvents. Use only
methanol and water.
