CAUTION

Sharp Tip of the Nebulizer

The capillary inside the nebulizer that protrudes from the nebulizer tip is sharp and may be fragile. Touching the nebulizer capillary can cause personal injury and damage to the capillary.

  • To avoid personal injury, always wear safety glasses when handling the nebulizer.
  • Do not touch the nebulizer tip.
  • Handle the nebulizer with care.

CAUTION

Escaping Gas

Gas can escape from open gas connections when the detector gas flow and/or the gas supply is turned on. The escaping gas can pose a health and safety risk.

  • Make sure that the detector gas flow and the gas supply are turned off before you remove the nebulizer, disconnect the gas tubes or remove the gas filter assembly from the detector.
  • Turn on the gas supply and detector gas flow only when the nebulizer is installed, the components in the gas flow path are properly connected, and the protective cover of the gas filter assembly is installed.

NOTICE

The nebulizer is highly sensitive to contamination. Even minute particles on the nebulizer can lead to contamination and poor detector performance. Always wear powder-free gloves when you install or remove the nebulizer.

Preparations

  1. Flush the detector with the detector gas flow being turned on. For recommendations on flushing the detector, see Flushing the Detector Between Analyses.

  1. Turn off the pump flow and then the gas flow:

  1. Turn off the pump flow to the detector. Wait at least 5 minutes. During the waiting period, the detector drains any remaining mobile phase to waste.
  2. Turn off the gas flow on the detector.
  3. Wait until the system pressure is down to zero before you continue.
  4. Turn off the gas supply to the detector.
  1. Turn off the detector with the main power switch.

  2. Disconnect the inlet capillary from the nebulizer.

Follow these steps

  1. Turn the nebulizer by 90 degrees counter-clockwise in the opening until it releases from the two locking points.

    Mind the correct orientation of the nebulizer when it is unlocked:

  2. Unlocking the nebulizer

  3. Pull the nebulizer straight out of the nebulizer opening.

  4. NOTICE

    Avoid the nebulizer tip from touching the sides of the nebulizer opening, as this can damage the tip.

  5. Removing the nebulizer

  6. Install the dust seal plug to the opening for the nebulizer.

  7. If the nebulizer is to be transported: Pack the nebulizer:

  1. Carefully install the protective tubing to the nebulizer spray pipe. Do not to touch the nebulizer tip with the protective tubing, as it can damage the tip.
  2. Install the plug to the nebulizer flow inlet.
  3. Nebulizer with protective tubing and plug on the flow inlet

  4. Pack the nebulizer in its original packaging that it was shipped in.

To re-install the nebulizer, follow the instructions in Installing the Nebulizer.
