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

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.
