Abstract
There is provided a microparticle analysis apparatus including a sample channel configured to receive liquid containing a plurality of microparticles, a first pair of electrodes configured to form an alternating electric field in at least a part of the sample channel, a measuring part configured to measure impedance between the first pair of electrodes, an analyzing part configured to calculate property values of the microparticles from the impedance measured in the measuring part, and a determining part configured to determine whether data of the impedance measured in the measuring part is derived from the microparticles.

- a sample channel configured to receive liquid containing a plurality of microparticles;
- a first pair of electrodes configured to form an alternating electric field in at least a part of the sample channel;
- a measuring part configured to measure impedance between the first pair of electrodes;
