Abstract:
Provided is a liquid feeding method for removing bubbles from a solution introduced into a fluidic device, wherein: the fluidic device includes a flow path of a volume v, a first chamber having a volume V1 and connected to a first side of the flow path, and a second chamber having a volume V2 and connected to a second side, being different from the first side, of the flow path; V1, V2, and v satisfy Formula (1) and Formula (2), α is a solubility of gas in the solution at a temperature of the second chamber, β is a solubility of gas in the solution at a temperature of the flow path, P0 is a pressure of a surrounding environment of the fluidic device, ΔP is a bubble internal pressure rise value, where ΔP=4σ/d, σ is a surface tension of the solution, and d is a diameter of the flow path; and the liquid feeding method includes: disposing the solution at a first position opposite to the flow path with respect to the second chamber; pressurizing and feeding the solution so that the solution is transferred through the second chamber toward the flow path; and pressurizing and introducing the solution from the second chamber into the flow path.
