Hidden challenges to make sample preparation for chromatography greener, more convenient and more sensitive
Register for free :
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
