摘要:
To monitor functions in a micro-fluidic system having mutually similar parallel fluid paths, sensors (7) are assigned to the individual fluid paths (5) at the same respective locations, in order to measure a physical parameter that is influenced by the fluid stream in the fluid paths (5). The sensors (7) are connected to an evaluation device (10), which diagnoses a change in the operating state of the micro-fluidic system based on the differences in the parameters measured by the sensors (7).

A method of producing a low-odor emulsion includes: charging an aqueous polymer emulsion into a treatment vessel and supplying pressurized water vapor into the vessel through a supply passage, while maintaining the inside of the vessel in a state where water is boiled by bringing temperature of the aqueous polymer emulsion into a range of 50-90° C. and pressure in the vessel into 12 KPa to 57 KPa; and discharging water vapor in a gas phase part in the vessel and a volatile organic compound volatilized from the aqueous polymer emulsion to outside of a system. A ratio of an inner diameter of the vessel to an opening diameter of a supply opening for supplying the pressurized water vapor from the supply passage into the vessel is from 30 to 3000 for the inner diameter of the vessel relative to 1 for the opening diameter of the supply opening.

A microfluidic device for storing a reagent includes a single unit includes a first portion having a reagent storage chamber configured to hold a reagent. The device also includes a second portion having a reaction chamber configured to support the reagent during a reaction process to form a product. The device also includes a valve configured to isolate the reagent storage compartment from the reaction chamber when the valve is in a closed state.
摘要:
Fluid transport approaches are described that operate without the need for precise displacement of an actuator and with little or no sensing in the flow path. In certain implementations, a gas phase in a fluid reservoir is compressed by a pressure source such that releasing the pressure, such as by opening a valve to an intermediary conduit, displaces fluid to the intermediary chamber. Closing that fluid path and opening a different fluid path to a chamber at ambient temperature causes the fluid to be displaced to the chamber.

摘要:
A reaction container in which to mix a first chemical compound with a second chemical compound has a main body and a lid member formed oppositely on a top face side of the main body; a flow channel on the top face of the main body; and a labeling agent solidification section at an intermediate section of the flow channel to remove a solvent in a solution of the second chemical compound and solidify the second chemical compound. First and second chemical compound supply sections and a mixture discharge section are formed on the upstream and downstream sides of the labeling agent solidification section, respectively. The reactor is provided with a liquid sending unit to supply the first and second chemical compounds and reciprocally send a solution of the first chemical compound to an upper part of the second chemical compound solidified at the solidification section.
