Abstract
Calibrated particle analysis apparatus and method are provided. In the calibrated particle analysis apparatus, a gas exchange device and several flow controllers are disposed in front of a particle analyzer. Therefore, when the calibrated particle analysis apparatus is used, gases of a sample can be exchanged with a carrier gas suggested to be used with the particle analyzer. Hence, the accuracy of analyzing the particles can be increased, and possible hazards from dangerous or toxic materials can be avoided.
