Patent ID: 7777867

Claim:
A turbulent mixing condensation device adapted to condense a working fluid on particles from a sample gas to enlarge the particles, the condensation device comprising: a vapor generator comprising: a working fluid chamber containing the working fluid wherein a carrier gas directed through the working fluid chamber absorbs at least some working fluid to form a vapor containing working fluid; and a carrier gas chamber containing carrier gas; a vapor mixing device adapted to mix the vapor containing working fluid from the working fluid chamber with the carrier gas from the carrier gas chamber to produce a mixture of working fluid and carrier gas; and a condensation chamber comprising: an inlet adapted to receive the mixture of working fluid and carrier gas; means for turbulently mixing the sample gas containing particles with the mixture to produce a particle-containing gas; a condensation tube adapted to receive the particle-containing gas and promote condensation of the working fluid on at least some of the particles to produce enlarged particles; and an outlet for a gas containing enlarged particles.
