Metrology is a specialized discipline related to the science of measurements and permits us to understand the intricacies governing the accuracy of an analytical pursuit. Measures introduced to improve precision of a measurement and accuracy of an analytical result increase the reliability of the finding. However, confidence in any analytical result depends upon the overall validity of the result that is expressed as the "uncertainty". Uncertainty means doubt about the validity of the result of a measurement. Therefore, the pursuit of identifying the accuracy of analytical results with a clear insight into the sources and nature of analytical errors to be able to reflect on the measurement uncertainties is an essential component of metrology.
