6 Quick, Easy, Cheap, Effective, Rugged and Safe ( QuEChERS ) Approach for Determining Pesticide Residues. Lehotay S. Pesticide Analysis, Methods in Biotechnology. Eds. Vidal Martinez and A Garrido Frenich. Humana Press, USA. November 2004. <Link> This is a chapter that describes the QuEChERS method, published by one of the method s developers. In Table 1, it provides a list of pesticide analytes with high yield recoveries from QuEChERS , noting GC-amenable Pesticides , those preferentially analyzed by LC/MS-MS or those that can be analyzed by either technique.
