Removing and Checking the Nebulizer and Spray Chamber
WARNING
• Use organic solvent such as acetone and methanol in a well-ventilated place like
the draft.
• Handle acid carefully.
NOTE
Pure water used for cleaning is indicated as water that has been generated using the
ion-exchange method and a membrane filter, and has an electrical resistance of at least
18 MΩ.
WARNING
HF or organic solvents remaining in the spray chamber can be hazardous or
flammable if they come into contact with skin or are spilled on the tray. Before
removing the spray chamber from the spray chamber chiller, complete the following
procedures:
1 Wash the spray chamber by aspirating pure water at a high speed and flowing
the carrier gas.
2 Stop the carrier gas. Aspirate air through the peristaltic pump for 1-2 minutes
and confirm that all of the solution from the spray chamber has drained.
