Abstracts 1-75 In the environmental field, carbon and nitrogen content are of great importance in various applications. Researchers can assess the effects on the overall carbon cycle by understanding on a micro level the effects of carbon and nitrogen concentrations on biological life forms in various matrices, including soils and seawater. More importantly, scientists are recently gaining insight into the ability of nitrogen to influence carbon concentrations, or "fertilize", in either fresh or saltwater, a process known as eutrophication. In years past, although many strides were made in measuring carbon levels with high sensitivity, total nitrogen measurement was not as sensitive as well as proved to be time consuming. However, using the combustion oxidation method in conjunction with chemiluminescence detection, an analyst can simultaneously measure carbon and total nitrogen levels with high accuracy and sensitivity in less than four minutes.
