Which analyzer automation approach can use mixing paddles to stir?

• A. Discrete analysis
• B. Centrifugal analysis
• C. Continuous flow
• D. Dry chemistry slide analysis

Answer: (A)

Mixing is handled differently across automated analyzers. The use of mixing paddles to stir is a hallmark of discrete analysis, where each sample and its reagents occupy separate reaction vessels and can be stirred directly to ensure thorough mixing and complete reaction before measurement. In centrifugal analysis, mixing comes from spinning the contents, not from paddles. In continuous flow analysis, reagents are combined in a flowing stream and mixed through flow dynamics and coils rather than by stirring with paddles. In dry chemistry slide analysis, reagents are pre-deposited on slides and react as the sample rehydrates them, with little to no stirring. So the paddle stirring fits the discrete, vessel-based approach.
