Soot measurements

	Here we introduce and validate the operation of a Mobility Separator Electrometer (MSE), which classifies particles by their electrical mobility, using automatic adjustment of the voltage set-point, allowing autonomous measurement of the aerosol population’s average electrical mobility Theoretical and experimental validation of the aerosol electrical mobility separator electrometer.

	This paper was the culmination of joint work between R Nishida and T Johnson (PhD students) to produce a miniature sensor based on tandem americium chargers. They have since set up a company to commercialise related concepts.

	This paper in collaboration with TU Graz showed a prototype QEPAS sensor with good linearity for mass measurements of soot, but a limited signal to noise ratio for small particles.
