Professor Nicholas Snow
Sample preparation is the most important, yet often most neglected area of chromatographic training and method development. The world's finest gas and liquid chromatographs generally cannot overcome mistakes made prior to sample injection.
This webinar will focus on general principles of sampling and sample preparation for chromatography and an overview of key concepts for several major sample preparation techniques, including:
* Liquid-liquid and liquid-solid extractions (LLE and LSE)
* Static headspace extraction (SHE)
* Solid phase extraction (SPE)
* Sorptive micro-extractions (SPME and SBSE).
Discussion will directed toward seeing the commonalities among all extraction techniques and toward choosing the best technique for a given analytical problem. Fundamentals of sample and glassware handling will also be reviewed.
This webinar is directed toward analysts who use these techniques hands-on every day and to the laboratory managers who must teach, train and supervise them.
