Abstract
Apparatuses for increasing the effective size of gas-entrained particles in a particle detector are disclosed. In one embodiment, an apparatus comprises an evaporation chamber, a condenser in fluid communication with the evaporation chamber, and an inlet in fluid communication with the condenser for receiving a stream of sample gas containing gas-entrained particles. The evaporation chamber includes a heating element and a porous support surrounding the heating element. The porous support carries thereon a working fluid, and the heating element vaporizes the working fluid to form vapor within the evaporation chamber. The porous support may include a portion which extends into a working fluid reservoir.
Claims21
An apparatus for increasing the effective size of gas-entrained particles in a particle detector, the apparatus comprising:
- an evaporation chamber;
- a heating element and a porous support each of which is disposed within the evaporation chamber, the porous support carrying thereon a working fluid and the heating element configured to vaporize the working fluid to form vapor within the evaporation chamber;
- wherein the porous support surrounds the heating element;
- a working fluid reservoir disposed in the evaporation chamber, the working fluid reservoir being configured to hold a working fluid, wherein the porous support includes a portion which extends into the working fluid reservoir;
- a condenser in fluid communication with the evaporation chamber for receiving said vapor;
- the condenser having an outlet for connection to a panicle detector;
- and an inlet in fluid communication with the condenser for receiving a stream of sample gas containing gas-entrained particles;
- the apparatus being configured so that condensation of the vapor onto the gas-entrained particles in the sample gas takes place in the condenser to increase the size of the particles for detection by a particle detector.
