Wherein the PM2.5 cutter can adopt the PM2.5 cutter of the production of many good instruments of model, the model: ZR-I02B.
Speed selector principle: according to fLuo＝qvB,FElectric powerWhen charged particles enter the velocity selector, the lorentz force and the electric field force are opposite, when the two forces are equal, the particles horizontally pass through the velocity selector, otherwise the particles are deflected to the bipolar plate and absorbed. From qvB Eq, we can derive v E/B that can pass horizontally through the speed selector, and we can also get the speed of the particle we need to pass by adjusting E and B. When the ambient air passes through a PM2.5 cutter, the particles with the particle size less than or equal to 2.5 mu m are obtained. After the PM2.5 particles enter the speed selector, the ratio of E to B is adjusted to select particles with the speed of 16.67L/Min.
Wherein the physical quantities are given by way of illustration:

Principle of particle separator: after particles with the same standard speed enter a particle separator with a deflecting magnetic field, the particle speed v is the same, the magnetic induction intensity B is the same, R is in direct proportion to m/q, the deflected curvature radius of the particles with different specific loads (m/q) is different, the particles with different specific loads (m/q) hit different positions on a receiving plate, the curvature radius R value of each particle is measured through different positions and starting point positions on the receiving plate, the specific load (m/q) value of each particle is obtained, and the corresponding known particle is corresponding to the curvature radius R value. The bombardment intensity received by the receiving plate approximately represents the concentration of the particles, and the content ratio of each component can be approximately judged according to the concentration.
Wherein the physical quantities are given by way of illustration:
