1. Set the nebulizer argon flow to
0.6 L/min.
2. Place the sample capillary tubing in a beaker of deionized water and start the
pump at a rate of 1.5 mL/min.
3. Check the spray pattern on a paper towel. You should see a fine, even spray of
uniform sample droplets.
If the spray pattern is not even or the nebulizer is sputtering, the nebulizer tips should
be inspected for clogging and cleaned or replaced as necessary. See the following
procedure.
Complete replacement of the nebulizer/end cap assembly may be necessary if the
GemTips are not seated properly inside the cap (see the next figure) or if the end cap
does not fit properly on the spray chamber.
Disassembling the Cross-Flow Nebulizer
Disassemble the nebulizer if it is necessary to clean or replace the GemTips. The
Cross-Flow nebulizer has two GemTips. The sample tip is a clear sapphire and the
argon tip is a red ruby.
These tips are
not
interchangeable.
For this reason, we
recommend that you first remove one GemTip, clean or replace it, then remove the
other.
When checking the spray pattern of the nebulizer, pump only use
deionized water. Do
not
use any other solution.
Avertissement:
Lors de la vérification du motif de pulvérisation du
nébuliseur, pompe utiliser uniquement de l'eau déminéralisée. Ne pas
utiliser toute autre solution.
