Particle spectrometer, especially for submicronic particles. |
摘要 |
<p>The spectrometer includes an electrical mobility selector which consists of two concentric discs (18,20). One of the discs (18) presents a circular slit (22) through which an aerosol to be analysed enters the appts. A central suction tube (26) extracts a gas sample from the space between the discs. The discs are conductor and connected to a power source thus generating an electric field (E). A similar circular slit (28) is provided on the second disc (20). A jet of filtered air is injected in the space delimited by the two discs. A mechanical collector 917) traps particles with electrical mobility equal to an adjustable threshold value (Z). <IMAGE></p> |
