Abstract:
1. A probe which forms a droplet containing an effluent and an additive solution, and allows the droplet to drop from a tip thereof, comprising a triple pipe structure in which a plurality of pipes are placed concentrically, wherein the triple pipe structure comprises: (a) a pipe that is placed on an innermost side of the structure, and forms a tip of a capillary column used for separation in a micro-scale or nano-scale high-performance liquid chromatograph; (b) an additive supplying pipe placed as a second pipe from the inside, the additive supplying pipe being used for allowing the additive solution to be joined to the effluent from the capillary column; and (c) a mobile phase supplying pipe placed on an outermost side of the structure, through the mobile phase supplying pipe a second mobile phase, different from a mobile phase in the eluent, being allowed to flow; and the droplet contains the eluent, the additive and the second mobile phase.
