MICROCHIP AND SAMPLE INJECTION METHOD

摘要

Provided is a microchip capable of causing contact at the interface between a reaction sample and a polymer, even when using a higher pressure, wherein it is possible to avoid damage to the microchip even when using a highly viscous polymer. The microchip is equipped with a sample channel filled with the reaction sample, a capillary filled with the polymer, a bridge channel for connecting the sample channel and the capillary, and an air discharge unit having a prescribed volume and connected to the bridge channel.
