Maintenance
1. If you have not already done so, remove the nebulizer/end cap assembly from
the spray chamber.
2. Disconnect the sample capillary tubing by removing it from the pump tube.
3. Disconnect the nebulizer argon tubing at the gas fitting. Do not disconnect
nebulizer argon tubing from the end cap because the GemTip could fall out.
4. Inspect the inside of the end cap. If metal or salt deposits are found, clean the
cap using a dilute acid solution.
Removing the Sample Tip from the End Cap, N0780546
1. Loosen the nut on the sample inlet . Remove the nut along with the tubing piece
and ferrule. See the next figure.
2. Using your fingers, push the sample tip out from the inside of the end cap,
being careful not to damage it. Do not use any metal tools to remove the
nebulizer tips because this may damage the tips or end cap.
3. Inspect the sample tip. Clean the tip using soap and water or a dilute solution
of nitric acid. An ultrasonic bath may be used.
If you need to replace the sample tip, be sure to replace it with a clear GemTip.
GemTips must be purchased in a set (Part No. N0780676). They are not
available separately.
4. Inspect the O-ring (Part No. 09921045), replace if it is worn or cracked.
