Capillary electrophoretic apparatus, sample plate and sample injection method

摘要

An electrode plate (104) of a sample plate (100) is set on the body of an electrophoretic apparatus, while a plug (106) is inserted into a migration high voltage line connection hole (107) and connected to a high-tension distribution cable. Each well of a base plate (101) is inserted into a through hole of a well guide (103) and further press-fit and engaged into a cavity (105) of an electrode plate (104), for fixing the base plate (101) to the electrode plate (104). Thereafter a sample is introduced into each well (102) of the base plate (101) and an end of a capillary column is dipped into each well (102) for applying a migration voltage and electrophoretically injecting the sample into the capillary column.
