Abstract

A particle measuring and counting system employs an isokinetic diluter comprising a gas filter having a capillary tube extending through the middle of the filter. The capillary tube and filter are arranged to divide a stream entering the filter into an outer substream from which entrained particles are filtered and an inner substream containing a sample of the outer substream. The two substreams are mixed downstream of the capillary tube and the resulting diluted sample flows through the particle counting and measuring instrument.
