Abstract
A sample testing system has a chamber sealing, apparatus adapted to receive a chamber containing a fluid sample material and to seal portions of a chamber into segments. A reagent injector cartridge actuator is adapted to receive a reagent injector cartridge having at least one needle in fluid communication with a reagent reservoir, and to move a reagent injector cartridge to inject a quantity of reagent into a segment of a chamber. In certain preferred embodiments, a flow control device induces a flow of sample in a segment. A sensor generates a signal corresponding to a condition of the mixture.
