IONIZATION EMITTER, IONIZATION APPARATUS, AND METHOD FOR MANUFACTURING IONIZATION EMITTER

摘要

Provided is an ionization emitter which can reduce a dead volume without deteriorating separating capacity. An ionization emitter (2) is provided with a tip (1) composed of a columnar or conical porous self-standing structure, and a channel for supplying a solution sample into the tip (1) from the base end side of the tip (1). The channel is formed by filling a pipe line with a packing, and the tip (1) is exposed from the pipe line of the channel. The packing and the porous self-standing structure constituting the tip (1) have an integrated structure composed of a same porous body formed at the same time.
