ABSTRACT:
The fraction collector according to the present invention comprises a separating means composed of electrophoresis tracks to separate samples by electrophoresis, and a transferring means to transfer the separated components eluted from said electrophoresis tracks, a transferring means which comprises the capillary sample transferring tubes which are placed with their ends close to the ends of said electrophoresis tracks at the specified gap, and which transfers the separated components eluted from each electrophoresis track, a transport means to supply the buffer solution to said gap and to carry said separated component to said sample transferring tube by sheathflow of said buffer solution, a fractionating means to fractionate the separated components having moved inside said sample transfer tube, a detecting means to detect the elution of said separated component by detecting the light emitted from said separated component, and a control means to control said fractionating means based on the signal gained by said detecting means; thereby fractionating the separated components having moved inside said sample transfer tube, based on the signal gained by said detecting means.
