Reattaching the Babington Nebulizer and the End Cap
1 Reconnect the sample uptake tube if it has been removed.
When you disconnect the sample uptake tube from the nebulizer body,
reattach it in the following way to suppress the memory problem.

a Ensure that the edges of the sample uptake tube (0.5 mm i.d. x 1/16″ o.d.,
PFA) and the tube connector are flush with each other.
If not, complete the following steps,
1 Slide the tube connector so that about 5 to 6 mm of sample uptake
tube protrudes beyond the tube connector.
2 After cutting the excess length of the protruded tube, re- slide the tube
connector so that about 1 mm of sample uptake tube protrudes.
CAUTION
Wear gloves when handling the Babington nebulizer or the sample tube to avoid
getting oils from your hands on the surface of nebulizer. If contaminated with oil, the
wetability of the surface of the nebulizer is compromised and the signal becomes
unstable. Also, the spray part of the nebulizer is delicate. Do not touch.
