摘要：An apparatus for real-time measurement of mass, size and number of solidparticles of particulate matter in engine exhaust has a catalytic stripper (14) to remove atleast about 90% of a volatile fraction of the particulate matter and pass at least about95% of a solid fraction of the particulate matter, and a micro-dilution tunnel (50) to coolthe test medium after passing through the catalytic stripper (14) and prior to passingthrough a particle sizer and counter system (58). A method embodying the presentinvention includes removing a volatile fraction of the particulate matter carried in asample test stream and comparing the sample after removal of the volatile fraction witha second sample in which the volatile fraction has not been removed. The differencebetween the two samples represents liquid phase of the volatile fraction of the testedexhaust gas.
