WARNING
Confirm that the drainage is flowing. Check that the tube from the drain peristaltic
pump to the drain bottle is properly connected. You should see a regular pattern of
liquid and air as shown above.
WARNING
When the spray chamber drain is not pumped properly, excess flammable solvents
in the spray chamber may ignite and become explosive. Ensure that the spray
chamber drain is being pumped properly during analysis.
When introducing a sample that has a tendency to solidify, such as photoresist,
ensure that the spray chamber drain is being pumped properly and that the torch
injector is not becoming clogged.
WARNING
Drain tubing damage depends on the organic solvent type. It is strongly
recommended to replace every day before introducing organic solvent samples.
WARNING
Check that the drain tubing is not damaged every day. Otherwise there is an
increased risk of explosion.
WARNING
Pump out the solvent in the drain line after analysis. The lifetime of the tubing is
drastically reduced if organic solvent remains in the drain tubing.
WARNING
When pulling out the drain connector, remove it slowly so that the solvent left inside
the tubing does not scatter.
Pump out the solvent in the sample introduction lines, spray chamber, and drain line
after you finish an analysis. When solvent is left, the deterioration of the tubing is
hastened.
