  • Page 18: How The Atomizer Works

    The Atomizer comes in two models: Model 3075 and Model 3076. Model 3075 is equipped with a syringe pump for operation in the nonrecirculation mode; the Model 3076, used as a conventional recirculation atomizer, does not have a syringe pump. Either model can be modified to work in either mode.

  • Page 25: Model 3076 Atomizer In The Recirculation Mode

    The 1-liter bottle is pre-assembled for use in the recirculation mode. The cap has two fittings: one delivers solution to the atomizer block, the other returns excess solution to the bottle from the Atomizer. The smaller fitting has a hose barb on the outside; on the inside, this fitting is soldered to a stainless steel tube that protrudes into the bottle.

    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 34: Neutralizing The Aerosol

    A neutralizer operates most effectively on dry particles. The Atomizer may be used to atomize most solutions or suspensions. A few common applications of the Atomizer are described in Chapter 5 of this manual. Model 3075/3076 Constant Output Atomizer...
