Shedding new light on your environmental investigation using not so new advances in analytical chemistry – GeoPro Talks

Crude Oil GCxGC Weathering

Dr. Sandau is pleased to be presenting to the GeoPro Talks 2021.  His presentation, Shedding new light on your environmental investigation using not so new advances in analytical chemistry, we be given virtually on Wednesday May 26, 2021 at 10:00AM PST. To sign up go here.

Abstract:

Analytical chemistry continues to evolve with the ability to detect more and more things in samples at lower and lower concentrations.  Now, it is moving into the big data realm.  Why limit what you look for when you can measure everything?

Multidimensional chromatography has been continuing to progress since its first development in 1991 and the first commercialized instrument in 2002.  Since then, applications for its unique uses have been growing.  Comprehensive multidimensional gas chromatography (GCxGC) allows the separation and complete chemical characterization of very complex mixtures such as crude or refined petroleum hydrocarbon mixtures.

This presentation will explain how GCxGC chromatography works and how different detection systems can be used to quantify and characterize petroleum hydrocarbons in crude oil or refined products to help elucidate source, age, and weathering.
