Abstract
A condensation particle counter includes: a saturator formed therein with a first flow path for supplying vapor to air introduced from an outside; a condenser formed therein with a second flow path in which the air and the vapor introduced from the first flow path are condensed; and a detector for detecting droplets condensed in the condenser, wherein the second flow path is provided with a guiding portion for guiding condensate flowing downward along an inner surface of the second flow path to flow into the saturator.

A condensation particle counter comprising:
- a saturator formed therein with a first flow path for supplying vapor to air introduced from outside;
- a condenser formed therein with a second flow path in which the air and the vapor introduced from the first flow path are condensed;
- and
- a detector for detecting droplets condensed in the condenser,
- wherein the second flow path is provided with a guiding portion for guiding condensate flowing downward along an inner surface of the second flow path to flow into the saturator,
- wherein the inner surface of the second flow path includes:
- a first inner surface having a cylindrical shape;
- and
- a second inner surface positioned between the first inner surface and the first flow path and provided as a curved surface different from the first inner surface, and
- wherein the guiding portion includes a boundary line between the first inner surface and the second inner surface.

A condensation particle counting system comprising:
- a first condensation particle counter;
- a second condensation particle counter;
- and
- a control unit configured to individually control the first condensation particle counter to a first temperature and the second condensation particle counter to a second temperature that is different from the first temperature,
- wherein the first condensation particle counter and the second condensation particle counter each includes:
- a saturator for heating an inside thereof to a saturator heating temperature to generate vapor and supply the vapor to air introduced from outside the respective condensation particle counter;
- and
- a condenser for cooling an inside thereof to a condenser colling temperature to condense the air and the vapor introduced from the saturator,
- wherein the first temperature and the second temperature are both different from the saturator heating temperature and the condenser cooling temperature.
