A Self-Contained DOP Penetrometer with a Liquid-Injection Aerosol Generator.

Abstract

This report describes the design and construction details of an experimental model DOP penetrometer to be used in evaluating the efficiency of particulate filters and filter materials for protective masks. In the new design many of the deficiencies of the instrument presently used were eliminated. The instrument includes a novel aerosol generator in which a constant flow at the desired concentration is attained by metering liquid dioctylphthalate (DOP) from a hypodermic syringe with an infusion pump and spraying it into the generator by means of an electrostatic field.
