  • Page 7 This section gives instructions to promote safe and proper handling of the Model 3076 Constant Output Atomizer. The Model 3076 Constant Output Atomizer is designed to release aerosol to a system that is at atmospheric pressure. Therefore, the pressure at the outlet of the Atomizer should be maintained close to atmospheric pressure (below 10 psig).

    The Model 3076 Constant Output Atomizer, shown in Figure 1-1, generates submicrometer aerosols that can atomize most solutions or suspensions. The conventional mode of operation for the Model 3076 Atomizer is the recirculation mode. The atomizer can be modified to work in nonrecirculation mode if necessary.

    Figure 1-2 Model 3076 Schematic of the Atomizer Assembly Block The Atomizer may be used in either recirculation mode or nonrecirculation mode. In the recirculation mode, recommended for water-based solutions, the liquid is drawn in from a 1-liter bottle (supplied) and the excess liquid drains into the same bottle. In the nonrecirculation mode, recommended for volatile solvents, either an extra reservoir bottle or a syringe pump should be used.

    0.59 cubic centimeters per minute, the maximum operating time is about 1 hour. At higher feed rates, the particle concentration is higher and the operation of the Atomizer is more stable; however, the maximum operation time is naturally shorter. Model 3076 Constant Output Atomizer...

    5. To change the aerosol particle size, use a solution of different concentration. Flush the Atomizer with about 25 cubic centimeters of solvent and then refill the syringe with the new solution. (A thorough cleaning—which means disassembling the Atomizer—is usually unnecessary unless you change from a high-solute concentration to a low-solute concentration.) Prepare the Atomizer for operation as done in step 3.

  • Page 41 ⁄ The suspension is aspirated through the -inch-diameter tube from an open reservoir and excess suspension is returned to the same reservoir. A sonic probe is used to continuously disperse the particles in the hydrosol reservoir. Results show that the aerosol consists mainly of primary particles—the agglomerates that are fused together by the carbon black manufacturing process—and that the level of agglomerates is very low.
