Abstract
Provided is a centrifugal field-flow fractionation device in which a liquid sample is less likely to leak from a channel and attachment and detachment work of a channel member is facilitated. By integrally forming an outer peripheral surfaceand an inner peripheral surfaceof a channel member, the channel memberis configured as one hollow member having a channelformed inside. Thus, pressure resistance performance of the channel memberis improved, formation of a gap in the channelcan be prevented, and deterioration in sealing performance due to secular change is not generated. Accordingly, a liquid sample is less likely to leak from the channel. Further, since the channel membercan be handled as one member, attachment and detachment work of the channel memberis facilitated.
