摘要： A flow-through test cell is disclosed which features an electrical conductor disposed in non-contacting adjacency with an ionic sensing electrode and a porous liquid junction for improving signal-to-noise ratio. The electrical conductor provides a low-impedance path through the fluid which effectively neutralizes signal distortion due to impedance variations in the air-segmented, continuously flowing stream. The electrical conductor includes distended sections which fixedly position such conductor in the ionic test cell, whereby shorting contact with said ionic sensing electrode and said porous liquid junction element is prevented.

摘要： The present invention discloses an apparatus for the determination of chemicals in a sample flow, which includes in combination a hollow conical chamber having large and small diameter portions. An entrance conduit communicates with the large diameter portion of the chamber to introduce a sample flow into the chamber in a generally tangential direction and the sample travels in a generally spirally extending path to the small diameter portion. A first axially extending conduit is connected to the small diameter portion to provide for the exit of a heavier fraction of the sample flow from the conical chamber. A second exit conduit is connected in an axial manner to the large diameter portion of the conical chamber to exit a lighter fraction of the sample flow from the conical chamber. First and second spaced electrodes are positioned in the first exit conduit.

摘要： An electronic apparatus for continuously metering and recording the partial pressure of CO2 including a voltage sensitive meter and recorder. The meter is adapted to receive and read voltage generated by an electrode representative of the partial pressure of CO2 in a stream of liquid introduced to the electrode. The recorder is adapted to record the voltage output from the meter together with a compensating voltage or in the alternative to record a pre-determined voltage which may be set independently of the voltage output of the meter. Electronic circuitry allows the recorder to automatically monitor the electrode voltage together with a compensating voltage. The circuitry also allows the periodic recalibration of the voltage supplied to the recorder. The calibration and monitoring of the partial pressure of CO2 may be done either manually or automatically. The electronic circuitry generally includes resistive networks, power supplies, time delay units, solenoid coils and associated relays.
