Title: Flow-through ionic test cell

Abstract: 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.
