Nebulizers

PerkinElmer offers different types of nebulizers for a wide variety of applications.
For descriptions of the nebulizers and their different uses and advantages, refer to
Chapter 3, System Description. Part numbers and replacement parts for the
different types of nebulizers are listed on the next page.
Recommended flow rates for the nebulizers are given in the table below. If you find
that a flow rate is insufficient, this often indicates that the nebulizer has clogged
and requires cleaning. On GemTip and GemCone nebulizers, you should also
check that the argon gas fitting is properly tightened. If a space collar is used,
tighten the fitting with a wrench until you can no longer turn the knurled space
collar. If a space collar is not used, finger-tighten the fitting, then using a wrench,
turn clockwise 1/8-turn.
