Interpretive Summary: In this article, the author lists and discusses the reasons that old methodologies are commonly used in laboratories even though superior new methods and technologies are often available. The system of performance based methods is outlined as a way to facilitate the transition from old methods to more beneficial methods. A general approach to determine if it is worthwhile for a laboratory to switch methods is provided, and an example is described for the implementation of a multiresidue method of analysis for pesticides using supercritical fluid extraction. The information is presented in nontechnical language and is designed to provoke thought among users of old methods. This article will help to speed the implementation process of new technologies in regulatory agencies and the agricultural chemical and food industries, which will help them to save money, reduce manual labor, and increase their analytical capabilities.
