Uncertainty estimation method:
Particle uncertainty could be estimated with the use of an SMPS and electrometer sampling in-tandem with the vwCPC. This has been done previously to show the size cut-off for the CPC. Additionally, the manual states that particle concentrations are +/- 5% when total concentrations are over 200,000. This could be considered the maximum error.
