Which statement best describes the discrete analysis approach in analyzer automation?

• A. It uses random-access capabilities
• B. It can use mixing paddles to stir
• C. It is limited to continuous-flow processes
• D. It requires a dry chemistry slide

Answer: (B)

Discrete analysis treats each sample as its own reaction unit, allowing individualized handling before measurement. A key feature is that you can stir the sample with mixing paddles inside its vessel, ensuring thorough mixing of reagents and the sample for a uniform reaction. This stirring capability is a practical hallmark of discrete systems, differing from continuous-flow approaches where mixing occurs through fluid dynamics as streams move through channels rather than in a separate, stirred vessel. A dry chemistry slide is simply one format used by some systems, not a defining requirement of discrete analysis. Random-access capability describes how samples can be accessed in any order, but it doesn’t define the approach itself. Therefore, the statement that discrete analysis can use mixing paddles to stir best captures its operational essence.
