Operating Manual
NOTICE—Sensitive Nebulizer
The nebulizer is highly sensitive to contamination and damage. Observe
the following safety notes:
• 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.
• The capillary inside the nebulizer may be fragile and subject to
mechanical vibrations during transport. If the nebulizer was
packaged separately, visually inspect the nebulizer surfaces and the
nebulizer tip prior to installation.
• Operating the nebulizer with a gas pressure other than the pressure
specified for this nebulizer can cause unpredictable deviations in
performance of the nebulizer and the detector. After installation of
the nebulizer, set the nebulizer gas pressure to the pressure that is
specified for your nebulizer. The nebulizer gas pressure is defined on
the gas pressure certificate that is shipped with the nebulizer.
• Powder-free gloves
• FocusJet nebulizer with dedicated nebulizer gas pressure certificate
• Optional: Deionized water
1. Wear powder-free gloves.
2. Remove the packed nebulizer from behind the detector doors.
