Differential Mobility Analyzer 3085A

SKU: 3085A

A key component of our Scanning Mobility Particle Sizer™ (SMPS™) systems.

Product Details

The Differential Mobility Analyzer Model 3085A is one of three Differential Mobility Analyzers (DMAs) designed for use with TSI Series 3082 Electrostatic Classifiers. This instrument is a key component of our Scanning Mobility Particle Sizer™ (SMPS™) Model 3938.

Series 3082 Classifiers allow you to swap DMA columns for additional versatility. If your Electrostatic Classifier already has a Long DMA, order the Model 3085A Nano DMA or Model 3086 1nm-DMA for additional particle sizing capabilities.

The Nano DMA was developed in cooperation with the University of Minnesota Particle Technology Laboratory and Gerhard Mercator University.
