Abstract:
1. A method of separation of chemical substances employing a multi-channel electrophoresis device, characterized by that: said multi-channel electrophoresis device is comprised of two pieces of left and right fixing apparatus each having a linear electrode; an electrophoresis chip with 2 or more electrophoresis channels that are capillary separation tubes; and storage tubs that are formed by compressing and fixing said electrophoresis chip by moving said left and right fixing apparatus from both sides; and said method of separation of chemical substances includes, a step of filling the capillary separation tubes with a buffer solution, a step of filling one of the storage tubs, which is at a side of sample introduction, with a non-polar solvent, a step of having samples ejected from sample ejection tubes to front sides of the corresponding capillary separation tubes and then having the samples not diffused in the non-polar solvent but injected directly into said capillary separation tubes of said electrophoresis chip by applying a voltage to the metal parts of the end parts of said sample ejection tubes in said one of the storage tubs, and a step of replacing the non-polar solvent with an electrophoresis buffer solution and applying an electric field to said linear electrodes, wherein said multi-channel electrophoresis device has no individual sample wells.
