High Concentration Standard Aerosol Generator.
Abstract
Under this contract Southern Research Institute (SoRI) has developed the High Concentration Standard Aerosol Generator (HCSAG) system with novel and frequently needed capabilities: high concentration, high flowrate, narrow size distribution, and particle size greater than 1 micron. This report describes the development of the HCSAG and serves as the instrument manual for the instrument. Section II (Operating Principle) gives the design criteria as well as describing the basic mechanisms upon which the HCSAG is based. Section III (Description of HCSAG) describes the actual components. Section IV (Performance Evaluation) presents aerosol data obtained during the course of developing the instrument. Section V (Operating Instructions) gives procedures for operating the HSCAG and Section VI (Maintenance) describes the procedures recommended to keep the components in good working condition. Section VII (Recommendations for Extending Performance) suggests procedures by which the system output could be modified to be more appropriate for given circumstances. These modifications include 1) increasing the concentration (if a lower flow or a wider size distribution is acceptable and 2) precautions and suggestions for use of different aerosol materials. Additional details of the system (including shop drawings, lists of materials, and maintenance of commercially available components) are given in Appendices A and B and are referred to in the text of this report.
