Chromatography Corner Environmental Geochemistry: Crude Oil Analysis LCGC spoke to Paul A. Sutton, a research fellow in the Petroleum and Environmental Geochemistry Group (PEGG) at Plymouth University, about the analysis of crude oil and how high temperature gas chromatography can be used to save millions of dollars for the oil industry. More...   Advanced Understanding of Our Climate As our climate experiences ongoing changes, scientists work to understand how seasonal cycles have evolved over the past tens of thousands of years to determine how they will continue to evolve. Dr. Ailsa Benton of the British Antarctic Survey is on the front lines researching changes in the climate. Learn how Dr. Aisla Benta utilizes Ion Chromatographs to analyze ice cores drilled from Antarctica.   Chromatography News GC–MS Detects and Identifies Four Ozone Depleting Gases in Atmosphere Four new ozone-depleting substances (ODSs) — CFC-1121, CFC-112a, CFC-113a, and HCF-133a — have been detected and identified in the Earth’s atmosphere using gas chromatography–mass spectrometry (GC–MS). The research published in Nature Geoscience compared samples collected between 1978 and 2012 to establish a clear increase in the emissions of these gases, even though CFC production has been banned globally since 1987.

The effect of the mobile phase parameters (NH4OH, CH3CN, and Na2CO3 concentrations) on the retention factors has been studied in detail, and the separation of the seven analytes was achieved using gradient elution. More...   Chromatography Solution Center Resources for Environmental Analysis We all know that environmental analysis is full of complexity.
