Title:
PARTICLE RECOVERY DEVICE AND PARTICLE RECOVERY METHOD
Document Type and Number:
Japanese Patent JP2023032349
Kind Code:
A
Abstract:
To reduce fluctuation of a recovery rate, by recovering tangible components contained in liquid samples having various densities, with stable recovery rates.SOLUTION: A particle recovery apparatus for recovering particles contained in a liquid sample, comprises: a flow cell having a channel through which the liquid sample flows; standing wave generation means that irradiates an ultrasonic wave that sweeps between a second frequency that is lower than the first frequency, which is the frequency of ultrasonic waves that generate a standing wave having a predetermined number of nodes in the channel, and a third frequency that is a frequency higher than the first frequency, into the channel; and recovery means for recovering the focused particles in the channel by the standing wave generated by the standing wave generating means.SELECTED DRAWING: Figure 1
