Abstract
An analytical cartridge adapted for use in analyzing fluids which contain liquid and solid components. The cartridge includes a plumbing system composed of various wells or chambers which are interconnected by passageways. After introduction into the cartridge, liquid samples are separated and transported to a test well utilizing a sequential application of centrifugal force followed by pressurization of the system. The cartridge may be used to measure the concentration of a wide variety of chemical constituents in bodily fluids and is useful in measuring other properties of these fluids which contain liquid and solid components.
