  • Differential mobility analyzer, particle measuring system, and particle sorting system
    Patent number: 8698076
    Abstract: In order to provide a differential mobility analyzer and the like that allows (i) easy increase of an upper limit of particle size of charged particle which can be classified and (ii) analysis of charged particles whose particle size is variable, a DMA (Differential Mobility Analyzer) includes: a classification tank in which an inlet electrode having an inlet slit, an intermediate electrode having a slit, and an outlet electrode having an outlet slit are arranged in sequence in such a manner that adjacent electrodes are disposed opposing each other at predetermined intervals; a gas supply section supplying the classification tank with sheath gas; and a voltage generator applying a predetermined voltage between the electrodes disposed opposing each other, the classification tank including a first classification section and a second classification section each formed by the electrodes disposed opposing each other, and the gas supply section controlling a flow rate of the sheath gas to be supplied to the classif
