  • Publication number: 20160025610
    Abstract: A measurement apparatus includes a generation section and a measurement section and performs a predetermined measurement using a flow channel device including a narrow channel through which particles pass by a flow of a fluid and a measurement electrode section provided in the vicinity of the narrow channel. The generation section generates, in the measurement electrode section, an AC voltage that is higher than a characteristic frequency defined by a conductance of the fluid including the particles in the narrow channel and an electrical double layer capacitance formed by the measurement electrode section and has a frequency range indicating a conductance corresponding to a size of the particles. The measurement section measures, while the AC voltage is applied to the measurement electrode section, an electrical amount including at least the conductance obtained when the particles pass through the narrow channel.

  • Patent number: 9211548
    Abstract: 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.
