Which analyzer type allows multiple tests on a single sample and also batch analysis of tests on multiple samples?

• A. Centrifugal analyzer
• B. Continuous-flow analyzer
• C. Discrete analyzer
• D. All of these

Answer: (C)

The ability to handle multiple tests on one sample while also processing many samples in parallel comes from using discrete reaction vessels that are isolated from one another. In a discrete analyzer, each test is performed in its own cuvette, and you can dedicates several cuvettes to the same sample to measure different analytes. At the same time, you can load a batch of samples (each with its own set of cuvettes) and run them through the system in parallel, so many samples are analyzed at the same time. This combination of isolated reactions and parallel processing is what makes the discrete analyzer uniquely capable of both multiplexing tests on a single sample and batch testing across many samples.

Centrifugal and continuous-flow analyzers are optimized for high throughput and have different modes of multiplexing that are less inherently suited to performing a wide variety of tests on a single sample in parallel, while still handling large numbers of samples through a common flow path or rotor.
