title: Precision aerosol divider.
abstract: A precision aerosol divider with a 17 to 1 flow split has been designed and tested. The divider, primarily a mass monitor calibration device, collects 94.4% of the aerosol on a filter to serve as a standard and delivers 5.6% of the aerosol to the mass monitor to be calibrated.
