Adjusting the sprayer tip position

To adjust the tip position
1. Adjust the X, Y, and Z controls on the adjuster assembly to move the
sprayer tip close to the sampling cone and baffle.
2. Adjust the height of the sprayer so that its tip is level with the center of
the baffle.
3. Adjust the horizontal position of the sprayer 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.
