Claim 33:
34. A system to determine false-particle counts in a condensation particle counter (CPC), the system comprising:
at least one wick having at least three aerosol flow paths formed therein, the at least one wick comprising a porous media;
a plurality of optical particle detectors, one of the plurality of optical particle detectors coupled to each respective outlet of one of the at least three aerosol flow paths to measure counts from the respective ones of the at least three aerosol flow paths; and
a processor coupled to each optical particle detector to compare a count from one of the at least three aerosol flow paths with a count of remaining ones of the at least three aerosol flow paths to make a determination whether the count from the one of the at least three aerosol flow paths is statistically greater than the counts of the remaining ones of the at least three aerosol flow paths, the statistically greater count being considered to be a false count.
