This proposal outlines a replacement request for a piece of analytical equipment that will allow introduction of samples to an Isotope Ratio Mass Spectrometer through an Elemental Analyzer prep system for the purposes of quantifying stable isotopic ratios of nitrogen and carbon in soil and other solid samples. This research is expected to generate important information about how we measure and understand the cycling of nitrogen and carbon in ecosystems that are affected by human activities related to landuse changes and climate change.

本提案概述了更换一台分析设备的请求，该设备将允许通过元素分析仪准备系统将样品引入同位素比质谱仪，以便量化土壤和其他固体样品中氮和碳的稳定同位素比。 这项研究预计将产生重要的信息，说明我们如何测量和理解生态系统中的氮和碳循环，这些生态系统受到与土地利用变化和气候变化有关的人类活动的影响。
