Particle analyzer |
摘要 |
A particle analyzer includes a flow cell for enclosing an electrolyte flow containing particles in a sheathed flow, the flow cell including a first and second cells which are interconnected through an orifice, the sheathed flow flowing through the orifice from the first cell to the second cell, a first and second electrodes provided in the first and second cells, respectively and a voltage application device for applying voltage between the first and second electrodes. The particle analyzer further includes a resistance detection device for detecting a variation of electric resistance between the first and second electrodes when the particle passes through the orifice to output the detected variation as a resistance detection signal. A first diameter calculation device is included for calculating each diameter of the particles based on the detected variation of electric resistance. Further a light source device for emitting a light beam to the particles enclosed in the sheathed flow and a light detection device for detecting each intensity of scatter light of the particles irradiated with the light beam to output the detected intensity as a scatter light detection signal are included. Finally, the particle analyzer includes a refractive index calculation device for calculating a refractive index of the particle based on the resistance detection signal and the scatter light detection signal and a second diameter calculation device for calculating each diameter of the particles based on the calculated refractive index and the scatter light detection signal.
