    C H A P T E R 1 Product Overview This chapter describes the Model 3080 Electrostatic Classifier, shown in F igure 1-1, and gives an overview of how the Classifier 2 4 0 H works. P r o d u c t D e s c r i p t i o n The Model 3080 Electrostatic Classifier can be used with either Differential Mobility Analyzer (DMA): Long or Nano, as the main component for generating or sizing aerosols.
  • Page 23 Collectively, the family of Electrostatic Classifiers size-classifies highly monodisperse, submicrometer aerosols in the range from 2 to 1000 nanometers in particle diameter. The Electrostatic Classifier is most often used as an integral part of a monodisperse- aerosol generation system or a submicrometer-particle sizing system.

  • Page 25: System History

    Polydisperse, submicrometer aerosol passes through a radioactive bipolar charger, establishing a bipolar equilibrium charge level on the particles. Particles receive either positive, negative, or zero charge(s). The particles then enter the DMA and are separated according to their electrical mobility. This parameter is inversely related to particle size and proportional to number of charges on the particles.

    W A R N I N G The Model 3077A/3077 Aerosol Neutralizer, which is installed inside the Model 3080 Electrostatic Classifier, contains radioactive material that is subject to the regulations of the U.S. Nuclear Regulatory Commission and local regulations. Carefully read the enclosed Model 3077/3077A Aerosol Neutralizers Instruction Manual to determine your legal responsibilities regarding the neutralizer.

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.

    Nano DMA Mounting The Classifier uses a quick-connect bracket to mount any of the two TSI DMAs. This mount provides physical support for the DMA as well as electrical grounding for safety. C a u t i o n If, for any reason, you operate the Classifier with a DMA that is not installed in the mounting bracket, you must connect the base of the DMA to the chassis of the Classifier with a ground strap or provide independent earth grounding to the DMA for safety.

  • Page 39: Tubing

    N o t e If the Classifier is part of an SMPS system, when connecting the serial cable, make sure you connect the cable from the computer to the CPC. It should not be connected to the Model 3080 Electrostatic Classifier. The SMPS system requires the synchronization between DMA voltage and particle counts that the CPC provides.

    Exhaust Flow Fitting ⁄ The Exhaust Flow fitting is a -in straight fitting that allows connections for the bypass air exiting the Classifier for the Nano DMA or for the sheath air flow for all DMAs. This fitting is left open in Single Blower mode, or it is connected to the Excess Flow fitting on the Classifier in Dual Blower mode.

  • Page 50: Impactor High/Low

    Impactor High/Low The impactor fittings are used to connect an internal pressure transducer to the tubes connected to the impactor on the inlet of the Classifier. This allows you to display the aerosol flow rate on the front panel (based on a calibration stored in the Classifier for each impactor nozzle).

  • Page 51: System Description

    S y s t e m D e s c r i p t i o n The Classifier consists of several subsystems that are needed in addition to the DMA to process a polydisperse aerosol and provide a monodisperse output. The main subsystems include: impactor, sheath-air flow controller, neutralizer, high-voltage controller, and DMA.

  • Page 52: Impactor

    Impactor An impactor may be mounted on the outside of the Electrostatic Classifier (see F igure 2-5). The aerosol first enters an impactor, 2 7 0 H which removes particles above a known particle size by inertial impaction. For more information on impactor theory, see Appendix B, “...

    instead of 10 millicurie) as that of the 3077A so it is sufficient enough to achieve charge equilibrium for low concentration aerosols for example ambient aerosols. High-Voltage Controller The High-Voltage controller provides a charge on the center rod of the DMA. This high voltage is controlled by the microprocessor based on the desired setting from the front panel and monitored by a sensitive high-voltage divider.

(4.987 cm). The characteristic length is defined as the length between middle of inlet slit to middle of outlet slit.

  • Page 58: Schematic Diagram Of The Model 3085 Nano Dma

    To improve the flow field at the sample slit (in the center electrode), the exit design for the Nano DMA is four thin supports instead of twelve holes for the Long DMA. The lower section of the center electrode also contains concentric cylinders. The inner cylinder allows the sheath air to pass up to the top of the DMA while the outer cylinder carries the monodisperse sample flow from the exit slit to the exit port.

    I m p a c t o r 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 approximation of the bipolar charge distribution on submicrometer particles has been taken from the work of Wiedensohler [1986, 1987] and Wiedensohler and Fissan [1988].
