REAL-TIME PARTICLE COUNTING METHOD AND REAL-TIME PARTICLE COUNTER USING CONDENSATION AND CHARGING METHOD

摘要

In the present invention, the correlation between the condensation grown individual particles of the same size and that in particular the ultrafine particles have the same and amount, respectively, to the total amount or concentration of the current and the measured particles, especially micro particles, determined therefrom proportionally that the data processing according to the basis of carrying out, discloses a real-time particle counting method, and real-time by condensation particle counter and the charge control method. Condensation and how real-time particle counting according to the charge control method, and real-time particle counters according to the present invention, unlike the prior art, it is possible to simplify a relatively accurate measurement of the number concentration of the particle size range desired in the air in real time, to use a laser, such as an optical system therefore, even without the contamination concerns of the optical system moving, so there is no restriction on the movement, and also, costs are low, and the structures and and operation to achieve a simple, that effect, and further the particles in particular the ultrafine particles to be measured in the atmosphere determining the particle size range and optionally, as a gaseous substance so are not converted into a particulate, to select only the particulate matter to the desired particle size range to achieve an effect of being able to perform quantitative measurements.
