stable surface.
Figure 7-3 Curtain Plate Removal
The curtain plate is held in place by three retaining ball catches mounted on the orifice plate.
Tip!
If the curtain plate does not immediately separate from the orifice plate, then turn the
curtain plate slightly, less than 90 degrees, to release the ball spring latches.
2. Dampen a lint-free wipe with LC-MS-grade water and then clean both sides of the curtain
plate.
Note:
Use multiple wipes, as required.
3. Repeat step
using the cleaning solution.
4. Using a dampened wipe or small poly swab, clean the aperture.
5. Wait until the curtain plate is dry.
