ABSTRACT:
To inject sample into an electrophoresis capillary tube having a separating medium, the end of the capillary tube is inserted in an injection block with a liquid tight seal and a syringe is inserted into the block to apply fluid to the end of the capillary tube. The injection block provides split flow injection. A high voltage isolated switching arrangement switches the end of the capillary from the injection block to buffer at a high electrical potential to accomplish the electrophoretic separation. A second injection block is used to purge the capillary tube and can be used to supply separating medium as needed.
