What is a control sample, and why is it important?

A control sample is a known standard that is used to validate the results of experimental samples. This sample serves as a benchmark against which the experimental results can be compared to ensure accuracy and reliability. When conducting laboratory analyses, it is critical to have a control sample because it allows analysts to determine whether the procedures they are using are functioning correctly and if the results they obtain are valid.

The importance of a control sample lies in its ability to help identify any potential errors, variations, or external factors that may impact the analysis. By including control samples in the testing process, analysts can enhance the credibility of their results, demonstrating that the findings are reproducible and reliable. This practice is fundamental in maintaining quality assurance in laboratory settings and ensures that experimental techniques are effective and consistent.
