  • Device for controlled injection of fluids
    Patent number: 4352780
    Abstract: A device for flow injection analysis wherein use is made of a double loop connected at opposite ends with flow control valves for alternate simultaneous injection of sample fluid in one loop while electrolyte fluid is injected in the other and for simultaneous alternate flow from one loop to an analysis station and from the other loop to a collector, and means for controlling the valves and pumps associated with the first valve for regulating the amount of sample fluid and electrolyte displaced through said valves.

  • Solution handling apparatus and method
    Patent number: 4272483
    Abstract: A solution handling device is disclosed which employs flow injection to maximize sampling rate with minimum reagent volume required per sample. The device employs two sample loops and a pair of solenoid actuated four-way valves for controlling flow through the loops. While a first loop receives electrolyte, a second loop, having previously received a sample, is channeled to an analyzer for a specified purpose. Subsequently, the valve operation is reversed so that operation is substantially continuous.
