Classification: CPC G  B | IPC B  G

Claim 8:
9. A particle matter analysis method comprising:
charging particles included in intaken air;
collecting particles having an electrophoretic mobility greater than a predetermined electrophoretic mobility among the charged particles based on the electrophoretic mobility and measuring a current of electrophoretic mobility particles;
collecting charged particles passing through an electrophoretic mobility particle collector based on an inertial force of the charged particles and measuring a current of aerodynamic particles;
collecting charged particles passing through an aerodynamic particle collector and measuring a current of filtered particles; and
calculating a density of the particles based on a ratio of the current of electrophoretic mobility particles, the current of aerodynamic particles, and the current of filtered particles.
