Abstract
A slide cartridge for use with a chemical analyzer includes an upper ring and a lower ring secured together but rotatable with respect to each other. The upper and lower rings define a plurality of reaction chambers between them, which receive dry analyte test slides. A gear track formed in the underside of the lower ring engages a pinion gear attached to a stepping motor of the chemical analyzer in order to rotate the slide cartridge. The slide cartridge is rotated under a sample fluid metering device, which deposits a sample fluid on the test slides through a plurality of spotter ports formed in the upper ring, and above a reflectometer, which performs a colorimetric measurement on the spotted test slides through viewing windows formed in the lower ring of the slide cartridge. A chemical analyzer with which the slide cartridge may be used includes a reflectometer, a sample fluid metering device and a stepping motor for rotating the slide cartridge.
