Hidden Challenges in Making Sample Preparation for Chromatography More Green, More Practical, and More Sensitive



Wed, Sep 21, 2022 11:00 AM EDT Join us to learn what to consider when seeking to make your sample preparation and chromatography methods more sensitive, more practical, and more green and sustainable — all at the same time (a bit of a challenge).

Event Overview:

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

Key Learning Objectives:

  • Understand the compromises of trying to make sample preparation for chromatography both more sensitive and more practical
  • Learn what to consider when seeking to make your sample preparation and chromatography methods more green and sustainable
  • Become aware of the experimental uncertainties that can be introduced by classical sample preparation techniques

Who Should Attend:

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

Nicholas H. Snow is the Founding Endowed Professor in the Department of Chemistry and Biochemistry at Seton Hall University and an Adjunct Professor of Medical Science. During his 30 years as a chromatographer, he has published more than 70 refereed articles and book chapters and has given more than 200 presentations and short courses. He is interested in the fundamentals and applications of separation science, especially 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 including headspace, liquid–liquid extraction, and solid-phase microextraction. He is also the editor of the “GC Connections” column in LCGC.
