Inter-laboratory calibration for the quality control of pesticide analysis (1982–1983)
Abstract
The organisation and running of six inter-laboratory exercises in South Africa in 1982 and 1983 are described. Analyses were carried out on solutions of pesticides, on residues in orange and cabbage pulp samples, peanut butter and preserved cream, and two formulations. The results indicated that most laboratories performed well but that some should strive to improve their analytical capabilities.
