Performance Problems
The sodium bullet test is also a good way of visually checking the sample flow in
the plasma and, therefore, indicates problems in sample introduction. See the
Sodium Bullet Test on page 319
.
Pump and Pump Tubing
Is the tubing overstretched or does it have flat spots, leaks, or discoloration?
Install new tubing, stretching it gently beforehand. If using organics, special tubing
should be used. See the list of
Replacement Parts: General on page 299
Is the flow of liquid irregular?
Refer to the procedure
Adjusting the Pump Tubing on page 292
.
Do the pump rollers bind or not roll easily? Are there grooves in the pump rollers?
On the PerkinElmer pump, the pump head may be removed for cleaning. The pump
head may also be replaced. See
Capillary Tubing
Are the nebulizer and sample capillary tubing properly connected? Is the tubing
discolored or clogged? Is tubing crimped or pinched?
If the capillary tubing is not in good condition, replace it.
Nebulizer and Spray Chamber
Is there leakage around the end cap? Is there leakage from the spray chamber
drain? Is fluid accumulating in the torch?
Make sure the end cap is on securely. If you cannot get a secure fit, the end cap O-
ring may need to be replaced. Check the drain fitting and tubing to be sure the spray
chamber is being properly drained. Check that the waste is being pumped in the
proper direction.
Check the nebulizer spray pattern: run deionized water for several minutes, then
remove the nebulizer end cap. Is the nebulizer spray sputtering or uneven?
If the spray pattern is uneven, the nebulizer tips may be clogged or worn.
Disassemble the nebulizer and clean or replace the GemTips. See
