Title:
【発明の名称】少量の液体試料の形成および輸送の空気制御
Document Type and Number:
Japanese Patent JP2003503184
Kind Code:
A
Abstract:
A process and system are provided for forming and transporting precise small volumes of liquid samples by means of controlled gas pressures. As the controlled gas pressures are changed at a multiplicity of control points in the fluid circuit, transitions take place involving the transport of small liquid samples. This transport is arrested by the geometry of the fluid circuit to produce a new state, which state remains stable until another transition is initiated by a change in the multiplicity of controlled gas pressures. Various combinations of control elements are described for effecting formation of fixed liquid volumes, transporting, mixing, and removing entrained bubbles from small liquid samples.
