  • Low-cost stream switching system
    Patent number: 6536471
    Abstract: A novel stream switching system includes a unitary housing having a common stream path for a multitude of fluid streams from, for example, a process pipeline. A set of solenoids or other switches attached to the housing directly controls the flow of each fluid stream. Preferably, the solenoids are default-closed, low dead-volume solenoids that, unlike conventional low dead volume solenoids, are closed if not supplied with electricity. These solenoids are adapted to the wide temperature ranges encountered in the pipeline environment by increasing the voltage applied to the solenoids. The housing also preferably includes a pre-heat region to warm the sample to a desired temperature.
    Type: Grant
