This chapter contains applications for the Model 3076 Constant
Output Atomizer.

Materials such as sodium chloride, sugar, uranine, and methylene
sucrose are commonly used to generate solid particles.
The concentration of the solute determines the particle size of the
aerosol. Figure 5-1 shows the relationship between mean particle
diameter and the concentration of sodium chloride; use it as a
guide when preparing a solution for a specific size of output
aerosol.
Figure 5-2 shows the typical size distribution of sodium chloride
aerosols generated by the Atomizer. Figures 5-3, 5-4, and 5-5 show
the number, surface area and volume distributions of the sodium
chloride aerosol generated from a solution of 0.0001 gram of
sodium chloride per cubic centimeter of water. All of the particle
size distributions were measured with a Scanning Mobility Particle

. The geometric
standard deviation from these figures is from 1.6 to 2.0.
