E21-38: Sample Processing, Preparation, and Analysis the QuEChERSER Way

One-Day Course
Wednesday, November 17; 8:30am – 5:00pm

Dr. Steven J. Lehotay, USDA Agricultural Research Service

The “quick, easy, cheap, effective, rugged, and safe” (QuEChERS) sample preparation approach co-developed by the instructor in 2003 has become one of the most widely applicable techniques in the world for analysis of small molecules in a variety of sample types.  Thousands of studies using QuEChERS have been published, and more than 25 vendors market QuEChERS products.  The instructor has recently updated and expanded QuEChERS into an even more streamlined, high-throughput, mega-method concept known as QuEChERSER (more than QuEChERS, which also includes “efficient and robust”).  In this 1-Day short course, the instructor will detail the start-to-finish QuEChERSER concept from rapid sample processing, simple extraction, automated cleanup, and robust analyses for a wide scope of GC- and LC- amenable analytes using MS-based detection, including efficient data processing and effective QA/QC procedures integrated routinely into the protocols.  QuEChERSER is even more useful than QuEChERS for a broader range of applications, such as forensics, clinical analyses, and chemical residue monitoring in food and the environment.
