Contaminants such as dust, microorganisms, and chemical impurities can significantly impact the integrity of bioanalytical experiments. For example, dust particles can introduce foreign substances that interfere with analytical measurements. Microbial contamination can degrade samples, especially those of biological origin, and lead to erroneous results. Additionally, chemical impurities can react with analytes or reagents, causing false positives or negatives. Therefore, maintaining a clean and sterile environment is crucial for accurate bioanalytical analysis.
