Abstract
A centrifugal field-flow fractionation deviceincludes a rotation unit, a rotation sensor, a first vibration sensor, a second vibration sensor, and an imbalance amount calculation unit. When an imbalance occurs in the rotation unit, the imbalance amount calculation unitcalculates the imbalance amount, based on a detection signal from the rotation sensor, a detection signal from the first vibration sensor, and a detection signal from the second vibration sensor. That is, when an imbalance occurs in the rotation unit, the imbalance is calculated by the configuration in the centrifugal field-flow fractionation device
