Particle counter is a very popular product now.
It is very usable.
Its light source requires high stability, long life, and no interference.
It can analyze particle impurities with a particle size of 011 μm in gas; Ar2Kr laser particle counter can be used.
For the analysis of 0105μm particle size impurities, there are currently particle counters that can detect 01005μm in ultra-high purity gas
.
Condensation particle counters can measure nanometer-sized particles
.
A particle counter is an instrument used to measure the number and particle size distribution of dust particles per unit volume in a clean environment
.
It can be widely used in various provinces and cities drug inspection institutes, blood centers, epidemic prevention stations, disease control centers, quality supervision institutes and other institutions, the electronics industry, pharmaceutical workshops, semiconductors, optical or precision machining, plastics, painting, hospitals, environmental protection, inspection such as production enterprises and scientific research departments
.
Particles in the air will scatter when illuminated by light, a phenomenon called light scattering
.
Light scattering is related to factors such as particle size, light wavelength, particle refractive index, and particle absorption characteristics of light
.
However, in terms of scattered light intensity and particle size, there is a basic law that the intensity of scattered light by particles increases with the increase of the surface area of the particles
.
In this way, the size of the particles can be inferred only by measuring the intensity of the scattered light, which is the basic principle of the light scattering particle counter
.
In fact, the scattered light intensity generated by each particle is very weak, which is a small light pulse.
It needs to be amplified by a photoelectric converter to convert the light pulse into an electrical pulse with a large signal amplitude, and then pass through the electronic circuit.
Further amplification and discrimination are performed to complete the counting of a large number of electrical pulses
.
At this time, the number of electric pulses corresponds to the number of particles, and the amplitude of the electric pulses corresponds to the size of the particles
