4-12 Configuring the NanoLockSpray source
6. Return the sprayer to its previous position.
7. Ascertain that sample is flowing by observing a droplet on the tip.
Tip: If you cannot observe a droplet, increase the pressure briefly, up to
a maximum of 1.5 bar, and then return the pressure to 0.3 bar.
8. If you observe a droplet, continue the procedure at step 9.
Requirement: If you do not observe a droplet, repeat step 4 through
step 8.
If, after you repeat step 4 through step 8, you still cannot observe a
droplet, discard the glass capillary and fit a new one (see page 4-9).
9. Set the capillary voltage slider to between 1.0 and 3.0 kV.
10. With an ion beam now visible on the peak display, optimize the sprayer
position and capillary voltage for maximum signal intensity.
Tip: The spray optimizes between 1.0 and 3.0 kV. To stop the sprayer,
set the capillary voltage to 0.
