Which chemistry analyzer is the only one described as DISCRETE?

The concept being tested is the difference between discrete and continuous-flow (or slide/dry chemistry) analyzer designs. A discrete analyzer processes each patient sample in its own reaction vessel (cuvette) with its own reagents, so every test occurs in a separate, isolated environment. This is what the Roche Integra is described as: a discrete analyzer that uses individual cuvettes for each test, allowing reactions to occur independently for each sample. In contrast, the Dimension RXL uses a continuous-flow/flow-path approach where reagents and samples move through a shared reaction sequence, not isolated cuvettes. The Vitros 950 relies on dry chemistry using slides, not discrete cuvettes for each test, and the ADVIA 1650 operates with a different flow-based chemistry design. Because only the Roche Integra is characterized as discrete, it is the best choice among the options.
