Why is calibration important for laboratory instruments?

Calibration is crucial for laboratory instruments because it directly relates to the accuracy and reliability of measurement results. When an instrument is calibrated, it is adjusted to align with a known standard or measurement. This process helps to eliminate systematic errors that might affect the data collected and ensures that the results are as close as possible to the true values. Accurate measurements are essential in laboratory settings, particularly in environmental testing, where precise data can influence decisions regarding public health and safety.

While proper sanitation of instruments is necessary for preventing contamination, it does not directly relate to the concept of calibration. Similarly, while increasing the speed of analysis could be a beneficial outcome in some contexts, it is not the primary focus of calibration. Lastly, although maintenance of equipment is an important aspect of laboratory operations, calibration itself does not inherently reduce the need for maintenance; rather, it is a separate process that ensures the instruments provide reliable data when used.
