Abstract

A process for counting and sizing particles in gases in the size range of 0.0025 micrometers or greater using condensation nucleus counting wherein the condensing temperature of a saturated working fluid is incrementally adjusted to adjust sensitivity to differing sizes of particles and thus discriminate according to size.
