Connecting the Model 3782, 3785, or 3786 WCPC
Use the procedures in this subsection to connect a Model 3782,
3785, or 3786 WCPC to the Classifier in underpressure or in
overpressure mode.
Model 3782/3785/3786 with Nano DMA
Refer to Figure 3-13 and the following instructions to connect the
plumbing between a Model 3080 Classifier with a Model 3085
Nano DMA and a Model 3782, 3785, or 3786 WCPC:
1. Locate the ¼-inch diameter (nominal) flexible tubing (3001903)
from the Classifier accessory kit and cut a length to 25 cm
[10 in.].
2. Locate the Flow equalizer assembly (1035989) from the SMPS
™
accessory kit and attach the straight portion of the tee to the
inlet on the back of the WCPC.
3. Position the WCPC so that the flexible tubing connects from the
DMA monodisperse aerosol outlet to the tee.
