Introduction to Sample Preparation

Presented by

Professor Nicholas Snow

About this talk

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.

The Year of Education came about through discussions between 3 professors who actively teach chromatography: * Professor Harold McNair, Virginia Tech, Blacksburg, USA * Professor Pat Sandra, University of Ghent, Belgium * Professor Peter Schoenmakers, University of Amsterdam, Netherlands "The first activity is a free webinar on gas chromatography, followed by a number of other activities, more webinars, online short courses, tutorials, instruction videos and much more! 2010 will be a year full of activities. Many experts will be involved, from university and industry. We believe all chromatographers should actively take part in this: in teaching, telling their employees and students to take courses. This is a chance they should not miss!"
