Abstract
Although the overall quality assurance concepts and goals for pesticide formulation analysis are similar to those required of an environmental or trace level analysis laboratory, some important distinctions exist, particularly for quality control. Generally, target levels (label values) are known and pesticide identification can be assumed, thus minimizing the need for verification of pesticide identity and for detailed confirmation of quantitative results reasonably close to the label value. Exceptions are cross-contaminant screening and by-product analysis. Quality control efforts in the formulation laboratory are concentrated on those samples falling outside the established acceptance criteria. The use of official (AOAC/Collaborative International Pesticides Analytical Council (CIPAC)) methodology, replicate determinations, second analyst confirmation, and alternative methodology (if necessary) is stressed. Specific attention must also be paid to the quality and preparation of analytical reference standards.
