Scientists all over the world have been monitoring the statistical distribution of weather patterns over extended periods of time to measure the potential affects and significance of climate change. This research not only studies past fluctuations, but also is used to predict future shifts in our climate and its global environmental impact.

The British Antarctic Survey (BAS) is a leading environmental research center that focuses on the United Kingdom’s national scientific activities in Antarctica. Some of their current research includes long-term monitoring of global climate change via ice core sample analysis of the polar ice caps in both Antarctica and Greenland.

Dr. Ailsa Benton, Ice Core Analytical Scientist at with the BAS, describes her research and how she and her team use a Thermo Scientific Dionex Fast Ion Chromatograph with dual channel system to increase throughput and analyze samples every 1.25 minutes in this video.

Additionally, she explains how BAS scientists are able to analyze essential anions at detection limits in the ice core samples and how this helps provide essential information on climate and environmental conditions to thoroughly monitor long-term global climate change.

Ion ChromatographyIon chromatography, also known as ion exchange chromatography, is a high-performance liquid chromatographic technique used for the separation and identification of ions or polar molecules in a sample, including proteins, nucleotides and amino acids. Equipment includes ion exchange columns, ion exclusion columns, ion chromatography systems, pumps, and detectors. Find the best ion chromatography equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Fluorescence SpectroscopyFluorometers and spectrofluorometers (also called fluorescence spectrometers) are used to measure the intensity and wavelength of fluorescent light emitted from a sample after excitation by illumination. Spectrofluorometers utilize monochromators to select the desired wavelengths, whereas filter fluorometers employ a set of filters. Spectrofluorometers for measuring steady-state fluorescence and lifetime fluorescence (or time-resolved fluorescence) are available, as well as fluorescence microscopes and microplate readers.

It provides detailed information about the structure, composition, and properties of compounds and is widely used across fields such as environmental monitoring, materials science, drug discovery and development, food and beverage testing, and wider chemical research. Key MS techniques include tandem mass spectrometry (MS/MS), liquid chromatography–mass spectrometry (LS-MS) and inductively coupled plasma (ICP-MS). Choosing from these wide range of techniques and technologies can be a daunting task, so keep up to date with scientific applications, performance expectations, and customer reviews here all in one place. Visit our product directory to receive quotes direct from the manufacturer. Environmental Monitoring and TestingEnvironmental monitoring and testing uses handheld portable analyzers, kits, spectrometers or chromatography systems for air, water, soil, food and other sample testing. Useful features of analyzers such as BOD and COD include portability, easy calibration, automation and sensitivity.  Environmental test kits for pH, water, moisture, etc, should be accurate, sensitive, reliable, fast and easy to use.Environmental AnalysisEnvironmental analysis describes a variety of tests that determine the effect of chemicals, processes and particulates such as persistent organic pollutants (POPs) have on the environment.
