Abstract: A soot generating device suitable for calibration purposes and a method of using the device for calibrating a soot measuring apparatus are presented. The soot generating device includes a wick located relative to a burning zone, a gas diffusion shield surrounding the burning zone that allows a continuous stream of air into the combustion zone, and a fuel supply for delivering fuel to the wick.
