  • Multiport rotary valve
    Patent number: 7377291
    Abstract: A multiport rotary valve has a stator with plural flow paths and a rotary valve plate having plural flow channels. The rotary valve plate defines a rotor that rotates relative to the stator to define unique plural fluid pathways from the stator, through the valve plate, and returning through the stator. Rotation of the rotary valve plate is controlled by a microprocessor, which includes an optical sensor to determine the position of the rotor.
    Type: Grant

  • Thermal conductivity detector
    Patent number: 7347080
    Abstract: A thermal conductivity detector (TCD) utilizes a modular thermistor assembly that mounts to the TCD body. The thermistor assembly is easily replaceable in the TCD. Within the TCD, a thermistor bead is always held in the same relative location in a gas flow path, which is designed to produce laminar, low velocity gas flow across the thermistor bead. Two TCDs, each having a heater, are mounted in an insulated enclosure. The heaters are activated to bring the TCDs to operating temperature, and are then deactivated during analysis.
