Document Type and Number:
Japanese Patent JPWO2021130922
Kind Code:
A1
Abstract:
A field flow fractionator (FFF device) 1 classifies particles in a liquid sample by applying a field to a liquid sample supplied from a sample injection device 5. A detector 6 detects the particles in the liquid sample classified by the FFF device 1. A bypass flow path 8 supplies the liquid sample from the sample injection device 5 to the detector 6 without via the FFF device 1. A rotary valve (flow path switching unit) 4 switches a flow path to guide the liquid sample from the sample injection device 5 to the FFF device 1 or a bypass flow path 8. The bypass flow path 8 is provided with a concentration adjusting device 9 for adjusting the concentration of the liquid sample from the sample injection device 5. In a case where a sample with the same quantity as the sample supplied to the FFF device 1 is supplied to the bypass flow path 8 at the time of analysis, the sample is diluted by the concentration adjusting device 9 such that a detection signal from the detector 6 falls within a dynamic range.
