Abstract
An apparatus and method for generating a controlled, predictable, reproducible and variable-size distribution of particulate matter (PM), particle number (PN) and/or facsimile/simulation, derived from vaporizing and condensing a specialized liquid, utilizing a vapor delivery device; a filter capability so as to remove a significant amount of ambient PM/PN as a secondary calibration process for the identification of fine and ultra-fine particles (e.g., 0.3 micrometers and smaller) as well as a computer-controlled ability to perform a pre-determined series of calibration routines, housed in a container.
