Quality Control System for Analytical Chemistry Laboratory of Pesticide Products

Many international organizations, such as the International Organization for Standardization (ISO) and Collaborative International Pesticide Analytical Council (CIPAC), have published a guide to quality control requirements, proficiency testing and method validation for pesticide formulation. In general, proficiency testing is to determine the performance of individual laboratories from the comparison of test results and to monitor a laboratory's performance abilities. One of quality assurance (QA) scheme would be include the validation of analytical method that implies a performance characteristics, specificity, selectivity, linearity and so on. According to many international organizations, the quantification methods of active substance in formulated pesticide products are required to be reproducible, accurate and precise. This study was conducted to compare the international guidelines for the quality control, proficiency testing and method validation of analytical laboratories and to propose a general guidance for the establishment of quality control system in the analytical chemistry laboratories of pesticide formulation in domestic.
