1. A measurement system comprising:
an atomizer having a liquid intake port, a gas intake port and an orifice, the atomizer configured to aerosolize a liquid received at the liquid intake port resulting in aerosolized liquid;
a virtual impactor having an inlet coupled to the atomizer and having a first output port and a second output port, the impactor configured to separate droplets such that droplets smaller than a selected size cut point are directed to the first output port and those droplets larger than the selected size cut point are directed to the second output port;
an evaporator coupled to the first output port;
a first particle counter coupled downstream of the evaporator and including a first input growth tube within the first particle counter, the first input growth tube configured with a first particle size cut point;
a second particle counter coupled downstream of the evaporator and including a second input growth tube within the second particle counter, the second input growth tube configured with a second, different particle size cut point; and
a discharge reservoir coupled to the second output port.
