ABSTRACT:
An electro-analytical cartridge adapted for use in analyzing fluids. The cartridge includes an electrochemical device that measures ionic activity using ion-specific electrodes. The cartridge further includes a plumbing system composed of the electrochemical device and various wells or chambers which are interconnected by passageways. After introduction into the cartridge, liquid samples are measured out and transported to the electrochemical device utilizing a sequential application of centrifugal force followed by pressurization of the system. Reference fluid is transported from a reference fluid well or reservoir to the electrochemical device for use in measuring ionic activity. The cartridge may be used to measure the ionic activity of a wide variety of ions in fluids including bodily fluids.
