1 Quality control

The purpose of quality control is to check that the analytical procedure functions correctly during routine use. It is designed to guarantee that no unrecognised changes during analysis influence the analytical result. Specific checking and monitoring procedures must be prescribed so that the person responsible for the analysis can be sure that the whole analytical system always yields tolerable results. With appropriate methods, important analytical, functional and statistical parameters are monitored to check that they remain within a given statistically determined range.
