Electrophoretically concentrating apparatus

摘要: An electrophoretically con concentrating apparatus containing a membrane material as support, wherein separating support (3) comprising water-retaining electrically connected to one electrode (5a) of DC power source is wet and swollen with buffer (A) leading ion and, at the same time, supports (7c) (9) are with, respectively, (C) following another being different in pH from for said support. In using apparatus, sample solution applied center linear form, both ends thereof illustrated, whereby total system under electric conduction. The gradually migrates (5a), during which it sandwiched between interfaces formed by on (9), thus once concentrated, then separated good accuracy (3).
