摘要： A flow channel device, a complex permittivity measuring apparatus, and a dielectric cytometry system are provided which can improve the measurement accuracy. A constriction portion having a constricted space is disposed between an inflow port and an outflow port of a flow channel. Electrodes are arranged between the inflow port and the constriction portion and between the outflow port and the constriction portion. The conductance of the constriction portion at a low-limit frequency is less than the combined conductance of an inflow channel portion and an outflow channel portion. The capacitance of the constriction portion at a high-limit frequency is less than the combined capacitance of the inflow channel portion and the outflow channel portion.

摘要： Disclosed herein is a cell sorter including a measuring electrode, working electrode, detection electrode, and output section. The measuring electrode forms a measuring electric field in a flow path to measure a complex dielectric constant of each cells flowing through the flow path. The working electrode forms, in the flow path, a working electric field to sort the cells by imparting a dielectrophoretic force to the cells and using the flow path. The detection electrode detects the presence of the cell in the fluid flowing through the flow path. The output section acquires a sorting signal based on information about the measured complex dielectric constant and a detection signal indicating the detection of the cell by the detection electrode. The output section outputs a working signal adapted to form the working electric field to the working electrode when the detection signal is acquired if the sorting signal is acquired.

摘要： The present disclosure provides an apparatus for sample introduction including a flow channel, a sample inlet, a metering unit, a separating unit, cell dischargers and, and a pressure controlling unit. The sample inlet is given a sample fluid such as blood. The sample inlet has a constricting hole that communicates with the flow channel for passage of a carrier fluid. The constricting hole has a diameter large enough for passage of a single cell contained in the sample fluid. The sample fluid is introduced into the flow channel through the constricting hole, and the cells in the sample fluid pass one by one through the constricting hole. The constricting hole does not exist inside the flow channel for passage of the carrier fluid, so that the diameter of the constricting hole does not affect the flow rate of the carrier fluid passing through the flow channel.
