Abstract
A field flow fractionator (FFF device)classifies particles in a liquid sample by applying a field to a liquid sample supplied from a sample injection device. A detectordetects the particles in the liquid sample classified by the FFF device. A bypass flow pathsupplies the liquid sample from the sample injection deviceto the detectorwithout via the FFF device. A rotary valve (flow path switching unit)switches a flow path to guide the liquid sample from the sample injection deviceto the FFF deviceor a bypass flow path. The bypass flow pathis provided with a concentration adjusting devicefor adjusting the concentration of the liquid sample from the sample injection device. In a case where a sample with the same quantity as the sample supplied to the FFF deviceis supplied to the bypass flow pathat the time of analysis, the sample is diluted by the concentration adjusting devicesuch that a detection signal from the detectorfalls within a dynamic range.
