Abstract
A particle recovery device for recovering particles contained in a liquid sample, the particle recovery device comprising: a flow cell having a flow path through which the liquid sample flows; standing wave generating means that applies, in the flow path, an ultrasonic wave that sweeps between a second frequency that is a frequency lower than a first frequency that is a frequency of the ultrasonic wave that generates a standing wave having a predetermined number of nodes in the flow path and a third frequency that is a frequency higher than the first frequency; and recovery means that recovers the particles focused in the flow path by the standing wave generated by the standing wave generating means.
Claims8
A particle recovery method of recovering particles contained in a urine sample, the particle recovery method comprising:
- applying, in a flow path, an ultrasonic wave that repeatedly sweeps between a second frequency lower than a first frequency that is a frequency of the ultrasonic wave that generates, in the flow path, a standing wave having a single node in the flow path through which the urine sample flows, the standing wave being generated in a direction orthogonal to a flow direction of the flow path when an averaged sample solution, obtained by mixing multiple urine samples with different densities, is caused to flow through the flow path, and a third frequency that is a frequency higher than the first frequency;
- and
- recovering the particles focused in the flow path by the standing wave.
