  • Patent number: 9823225
    Abstract: Described are a method and a system for diluting a sample at a location of injection in a liquid chromatography system. The method includes loading a sample into a first fluid channel, separating a flow of a mobile phase into a first flow in the first fluid channel and a second flow in a second fluid channel, and combining the sample that is displaced from the first fluid channel and the mobile phase exiting the second fluid channel at the location of injection into the system flow to thereby generate a diluted sample in the system flow. The dilution ratio of the diluted sample is responsive to the flow rates of the first and second flows. Advantageously, the flow rates can be changed by changing the flow restriction of one of the fluid channels. Thus providing the proper flow restriction enables a user to obtain a desired dilution ratio.

The method includes combining a flow of a sample and a flow of a mobile phase to create a diluted sample in the system flow. The volumetric flow rate of the sample is controlled to be at a value that yields a desired dilution ratio for the diluted sample. The particular value at which the volumetric flow rate is maintained can be determined from the desired value of the dilution ratio and the volumetric flow rate of the mobile phase. System embodiments include a syringe that can be used to provide a sample solution at a controllable volumetric flow rate for combination with a high pressure mobile phase.

    Abstract: A method and apparatus, for supplying high-pressure mixed gas of a low-vapor-pressure first gas as an active gas and a high-vapor-pressure second gas, are arranged to reduce an amount of the first gas discarded. The mixed gas in a high-pressure state is supplied from a mixing container to a use point. Upon reduction of pressure in the mixing container to a setpoint as a result of supply to the use point, a predetermined amount of the first gas is charged into a replenishment container connected to the mixing container by a replenishment line having a replenishment valve, and which is evacuated. As the second gas is charged into the replenishment container charged with the first gas, the replenishment valve is opened such that the first gas in the replenishment container is forced out by the second gas, thereby charging the mixing container with the mixed gas in the high-pressure condition.

    Abstract: Modular fluidic mixing system for delivering a fluid mixture from separate sources to a point of use. The system includes a mounting board and a series of rows of substrate fittings mounted on the board. Each row has a first end fitting connected to one of the fluid sources and a second end fitting. Each of the fittings in a row is connected in fluid communication to an adjacent one of the fittings in the row to define a fluid flow path from the one of the fluid sources to the second end fitting. Each second end fitting in each row is connected in fluid communication to an adjacent second end fitting in an adjacent row to define a mixing header. The fluids are mixed within the header and exit as a mixture. Fluid flow components for controlling flow from the fluid sources are mounted to the fittings.

  • Patent number: 8291935
    Abstract: Each of plurality of gas sources flows to a different one of a plurality of separate source gas flow paths. Then, a source gas is distributed directly from each of plurality of separate source gas flow paths to a plurality of separate gas mixture flow paths, thereby distributing a plurality of source gases to each of different flow paths. A plurality of separate gas mixture streams is generated by flowing a plurality of source gases in each of a plurality of separate gas mixture flow paths. In some embodiments, each of a plurality of separate source gas flow paths comprises a gas distribution duct, and each of a plurality of gas mixture flow paths comprises a gas mixing conduit. In some embodiments, a gas distribution duct includes a plurality of gas distribution ports and a gas source port connectable to a gas source. In some embodiments, a gas mixing conduit comprises a plurality of gas inlet holes, a gas mixing region, and a gas outlet hole.

  • Patent number: 7946504
    Abstract: An electronic faucet for mixing hot and cold fluids and a manual override system therefor. The override system is adapted to override the electronics of the faucet in order to allow a user to gain full manual control, for example, if the user merely desires it or there is a malfunction in the faucet's electronics or an electric power outage. The faucet can be operated in an automatic mode, a manual mode and switch between those modes. According to one embodiment, the override system disables the faucet's electronics as a result of manual movement of the handles causing a motor of the electronic faucet to deviate from its normal resistance or current, signaling the electronics to become disabled. According to another embodiment, pulling or pushing of the handles mechanically disengage them from the electronic control.

  • Patent number: 7740031
    Abstract: A gas blending and compressing system includes a blender having a blending chamber configured to blend two or more separate gases into a blended gas, a compressor configured to compress the blended gas to a selected pressure, and a control system configured to sense operational parameters of the blender and the compressor, to sense one or more properties of the blended gas and to control the operation of the blender and the compressor to maintain the quality of the blended gas. A method for blending and compressing two or more gases includes the steps of: blending the separate gases into a blended gas using the blender; compressing the blended gas using the compressor; and matching a constant flow through the compressor to a selected minimum flow dependent on nominal operating parameters of the compressor. Alternate embodiment systems and methods blend separate gases at high pressure without using a compressor.
