What is a characteristic feature of a discrete analyzer in laboratory settings?

A discrete analyzer is specifically characterized by its ability to process individual samples separately rather than in bulk, which is effectively what option C describes. These analyzers manage to dispense samples, mix reagents, and conduct measurements in a photometric fashion, ensuring that each sample undergoes its own individual assay process. This feature allows for greater control over each analysis and reduces the potential for cross-contamination between samples.

The ability to measure each sample separately makes discrete analyzers particularly useful in situations where different tests may need to be performed on diverse samples, enhancing flexibility and accuracy in results. This design also facilitates rapid processing times, as there is typically a reduced wait for results compared to other types of analyzers that may require batching of samples.

In contrast, while sequential processing and continuous analysis are methods used in laboratory settings, they do not define discrete analyzers specifically. Long-term storage of samples is unrelated to the functionality of an analyzer, which is primarily focused on analysis rather than sample preservation. Hence, the correct answer aligns directly with the operational mechanics of a discrete analyzer.
