Guest guest Posted August 9, 2004 Report Share Posted August 9, 2004 Dear Colleagues: Does anyone have any sugestions for generating a stable mix of aerosols in the aerodynamic diameter size range of a few microns. Can anyone suggest a suitable aerosol generator or nebulizer for this function? Sincerely, W. Bearg, PE, CIH Concord, MA 01742 Quote Link to comment Share on other sites More sharing options...

Guest guest Posted August 9, 2004 Report Share Posted August 9, 2004 Dave, Your request for a consistent micron size particle generator is a vexing problem that has existed for almost 50 years. There is considerable information in biowarfare texts on the development of chambers for doing this. However, they are quite large - about a 55 gallon drums, that is constantly rotated to keep the particles in suspension and to stop agglomeration. The only somewhat unit available is a dioctyl phthalate generator for testing HEPA filters. This generates a 0.03µ particulate. C. s, Ph. D, M.P.H., P.E., C.I.H., C.S.P.,CMR President, OEHCS, INC.

Guest guest Posted August 9, 2004 Report Share Posted August 9, 2004 Contact a contractor who does HEPA filter testing for such entities as hospitals.
