2-30 Electrostatic Classifier Model 3082 and SMPS Spectrometer Model 3938
10. Push the other end
of the tubing onto
the Polydisperse
Flow fitting on the
DMA.
Alternative Installation of the 1nm-DMA
To minimize diffusion losses between the 1nm-DMA and the Model 3777
Nano Enhancer, use the following instructions to mount the 1nm-DMA
horizontally and couple it to the inlet of the Nano Enhancer:
1. To use the Bypass flow (see Using Nano DMA or 1nm-DMA Bypass
Flow), remove the cap and connect the manifold outlet to a vacuum
line. If the Bypass Flow will not be used, leave the cap in place and
continue with step 2.
2. Using a Phillips head screwdriver, remove the baseplate from the
1nm-DMA. Snap the DMA base plate into the classifier so that it
autodetects the 3086 1nm DMA.
3. Set the 1nm-DMA onto the provided horizontal mounting bracket.
Using a Phillips head screwdriver and the included mounting screws,
attach the DMA to the mounting bracket.
4. Remove the stainless steel ¼” OD tube that is pressed into the outlet
port of the 1nm-DMA, leaving a female outlet port. Save this ¼” tube
for future use.
5. Remove the 3/8-inch black conductive tubing from the 3082 Accessory
Kit. Using the provided tube cutter, or a clean razor blade, cut two
24 in. lengths of tubing.
6. Push one end of each piece of tubing into place on the Nano DMA flow
manifold ports.
