A New Coincidence Correction Method for Condensation Particle Counters

Figures & data

FIG. 1 Detection of a coincident event.

FIG. 2 A plot of the Lambert W function.

FIG. 3 Theoretical response of counter calculated using approximations (Equations (7) and (8)) and the Lambert W function (Equation (10)).

FIG. 4 Experimental set up for measurement of particle concentration.

FIG. 5 Experimental λ_mτ_d and comparison with theory.

FIG. 6 Coincidence correction applied to MSP 1110 count data and comparison with approximations. The reference concentration was measured with a Faraday cup electrometer. The error bars represent 99% confidence intervals.

FIG. 7 Coincidence correction applied to TSI 3760A count data and comparison with approximations.
