Analytical Quality Control
Analytical Quality Control (AQC) is one of the main components of a Quality Assurance System, wherein the quality of analytical data being generated in any laboratory is controlled through minimizing or controlling errors to achieve a target accuracy. A particular water quality study or any organized water quality monitoring programme involves the collection, comparison and interpretation of analytical data, which leads to a decision for the management and use of water resource. The correctness of decision or actions depends largely upon the accuracy of the analytical results. If the errors in the analytical results are high, the manpower, material and money spent on any monitoring programme or study would be futile and further lead to wrong decision and improper action plans. Since the success and usefulness of any information system derived from analysis results depend on the quality of input data, it is essential to ensure that adequate comparability and accuracy of analytical results are achieved.
Objectives
The main objectives of an inter-laboratory Analytical Quality Control (AQC) programme are:
- to assess the status of analytical facilities and capabilities of concerned laboratories;
- to identify the serious constraints ( random & systematic) in the working environment of the laboratories;
- to provide necessary assistance to the concerned laboratories to overcome the short comings in the analytical capabilities;
- to promote the scientific/analytical competence of the concerned laboratories to the level of excellence for better output; and to enhance the internal and external quality control of the concerned laboratories.
Punjab Pollution Control Board is participating in the Analytical Quality Control exercise of Central Pollution Control Board since last one decade. Performance Report of Zonal Lab., Ludhiana under 34th AQC conducted by CPCB.
