Event overview:

Analytical chemistry method developers have always faced the challenge of making their methods more sensitive and practical. We are all aware of the trade-offs involved when attempting to do both at the same time, such as the often more complex instrumentation when optimizing a method for speed. Today, we face an additional challenge: to make analysis methods greener and more sustainable. In this webinar, we will discuss the experimental uncertainties that can be introduced into chromatographic methods using the most common classical sample preparation techniques, including weighing, filtering, pipetting, diluting, and making solutions. These techniques underpin all the other procedures we use, including techniques such as headspace extraction, solid phase extraction (SPE) and solid phase microextraction (SPME), the technique original “green” sample preparation. We will then look at additional challenges to making our classic techniques “greener,” including smaller sample volumes, fewer dilutions, fewer steps, and less solvent usage.

Key learning objectives:

  • Understand the trade-offs of trying to make sample preparation for chromatography both more sensitive and more convenient
  • Learn what to consider when looking to make your sample preparation and chromatography methods more environmentally friendly and sustainable
  • Become aware of the experimental uncertainties that can be introduced by conventional sample preparation techniques

Who should attend:

  • Analytical chemists developing methods using sample preparation techniques and chromatography
  • Chromatographers and lab managers wanting to learn more about sustainable and green approaches

Nicholas H. Snow, Ph.D.
Founding Endowed Professor, Department of Chemistry and Biochemistry, Seton Hall University

Nicholas H. Snow is the founding endowed professor of the Department of Chemistry and Biochemistry at Seton Hall University and Adjunct Professor of Medical Sciences. In his 30 years as a chromatograph, he has published over 70 peer-reviewed articles and book chapters and given over 200 presentations and short courses. He is interested in the fundamentals and applications of separation science, particularly gas chromatography, sampling, and sample preparation for chemical analysis. His research group is very active, with ongoing projects using GC, GC-MS, two-dimensional GC and extraction methods such as headspace, liquid-liquid extraction and solid-phase microextraction. He is also the editor of the “GC Connections” column in LCGC.
