Disconnecting the Babington Nebulizer from the End Cap
To disconnect the Babington nebulizer from the end cap, complete the
following steps:
1 Disconnect the carrier gas and makeup gas hoses.
Disconnect the carrier gas hose connector, also.
2 Disconnect the nebulizer from the end cap using the removal tool.
To remove the nebulizer, refer to the figure on the following page.
a Place the plate on the nebulizer end cap.
b Pass the nebulizer through the hole of the removal tool and slide the
removal tool so that it mates with the groove on the nebulizer body.
c Insert the two thumbscrews in the removal tool, and alternately tighten
the screws until the nebulizer pulls out of the end cap.
NOTE
Wear gloves when handling the Babington nebulizer to avoid getting oils from your hands
on the surface of nebulizer. If contaminated with oil, wetability of the surface of the
nebulizer is compromised and the signal becomes unstable.
The wetability of spray surface of the Babington nebulizer is significant for the signal
stability. If the signal is unstable, check the wetability of the surface of the nebulizer
visually after disconnecting the end cap from the spray chamber.
CAUTION
Be careful not to rotate the removal tool. This may damage or break the guide pin
attached to the nebulizer.
