PURPOSE: To perform analysis in a short time without requiring a number of stages of cleaning-up operations comprising solvent extraction, etc., even in the case of living body samples. CONSTITUTION: In this capillary electrophoretic chip 10, a wide holding part 14 packed with a packing material for pretreatments is provided in the center of a migration groove 13, and branching grooves 15, 16 are provided in the portions of the migration groove 13 in front of and behind the holding part 14. At the first stage, a component for analysis is held in the packing material in the holding part 14, and at the second stage it is eluted and separated through electrophoresis inside the migration groove 13. |
