TSI - Model 3940A -Submicrometer Monodisperse Aerosol Generator

The 3940A is a component-based system that is capable of generating monodisperse particles. The process flow within the 3940A goes as follows: 

• 3074B Filtered Air Supply - prepares house compressed air to be suitable for aerosol generation
• 3076 Constant Output Atomizer - generates aerosols from a solution or suspension
• 3062 Diffusion Drier - removes solvent (often water) from the particles exiting the 3076 Atomizer
• 3012 Neutralizer - conditions the charge of the aerosols, so that the charge distribution is centered on zero (neutral, uncharged particles are most populous)
• 3082 Electrostatic Classifier, 3088 Advanced Aerosol Neutralizer, and 3081A DMA - takes in the polydisperse aerosol from the preceding components, and emits only particles of the designated size. This `classifying` process uses the electrical mobility of the particles (using the minority of the particles that are charged) to determine their size.
