Adjusting The Sprayer Tip Position - Waters Xevo G2-XS QTof Overview And Maintenance Manual

Adjusting the sprayer tip position

To adjust the tip position:
1. Using the X-, Y-, and Z-position adjuster controls on the adjuster
assembly, move the sample-sprayer tip close to the sampling cone and
baffle (see the photo on
2. Move the sprayer so that its tip is level with the center of the sampling
cone.
Use the index mark on the adjuster to obtain the correct position.
Tip:
3. Move the sprayer horizontally, so that the tip points toward the
left-hand side of the baffle.
Tips:
• If you observe an electrical discharge between the sprayer tip and
baffle, move the tip farther from the baffle, or reduce the capillary
voltage. Note, however, that the capillary voltage must be high
enough to maintain a good spray.
• Fine-tune the position of the sprayer while acquiring a spectrum of
a standard compound. Small adjustments to the sprayer position
can make large differences to the source sensitivity.
