GemTip Cross-Flow Nebulizer
The following procedures cover the maintenance of the GemTip Cross-Flow
nebulizer supplied with the instrument.
To check the performance of the nebulizer, aspirate a standard and note the intensity
reading. If the intensity is significantly lower than it should be, first check that:
• The pump tubing is in good condition (has no flat spots).
• The sample capillary is in good condition (has no kinks) and is clean.
• The plasma viewing position is set properly (using the software's alignment
function).
Also try flushing out the nebulizer by aspirating for several minutes using either:
• a 1% acid solution, if you have been analyzing aqueous solutions, or
• a solvent, if you have been analyzing organic solutions.
Recheck the intensity of the standard. If the intensity is still too low, you should
check the nebulizer spray pattern. Before removing the nebulizer/end cap to check
the spray pattern, be sure to pump deionized water for several minutes to thoroughly
flush it out.
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 de la
pompe nébuliseur utiliser uniquement de l'eau déminéralisée. Ne pas
utiliser toute autre solution.
