4. Insert the neutralizer with the long tube up and the screws in
the side of the neutralizer aligned with the slots in the
neutralizer mounting block as shown in Figure 2-2.
5. Replace the outlet block in the Classifier and push down. If the
block does not fit over the neutralizer tubes easily, do not force
it—you will damage the O-rings and cause a leak—try steps 2
and 3 again.
6. Replace the screws in the outlet block. The outlet block should
be flush with the cabinet top and the pop-up flag indicating that
the neutralizer is installed should be visible as shown in
Figure 2-3.

Installing an Impactor
Depending on the Classifier package you ordered, an impactor will
be shipped as an accessory. The primary function of the impactor is
to remove larger particles that carry more than a single charge.
However, the impactor is also used as a flowmeter, since the
pressure drop across the impactor is proportional to the square of
the flow rate.
The impactor assembly is attached to the aerosol inlet of the
Classifier using a Swagelok

fitting. Make sure the downstream
