We are requesting a solid phase C, N, and S analyser (CHNS) with a built-in auto sampler and a high precision (0.00001g) analytical balance. The analyser will measure C and N concentrations in plant leaves, plant litter, soils, and sediments, with the findings linked to important terrestrial ecosystem level processes (decomposition, N mineralisation, general nutrient cycling)(Lindo, Henry), and data used to parameterize energetic food web models for detrital systems (Lindo). It will also be used to measure total C, N, and S and organic C in terrestrial soils and aquatic sediments in order to understand the fate and transport of environmental contaminants (Branfireun, Macfie). The CHNS system will also be used for innovative analysis of phytoplankton (Branfireun) and soil organisms (Lindo) that will provide novel contributions to these research programmes. Analysis of C, N, and S in plant tissues and litter, soils and sediments, and integral components of aquatic (phytoplankton) and terrestrial (soil organisms) food webs will allow us to support fundamental, cutting-edge research into controls on biodiversity, microbial decomposition, and Hg transformation spanning from biomolecular to ecosystem scales across Canadian ecosystems.

我们需要一个内置自动进样器和高精度（0.00001g）分析天平的固相C、N和S分析仪（CHNS）。该分析仪将测量植物叶片、植物凋落物、土壤和沉积物中的C和N浓度，研究结果与重要的陆地生态系统水平过程（分解、N矿化、一般营养循环）（Lindo，亨利）有关，数据用于碎屑系统的能量食物网模型参数化（Lindo）。它还将用于测量陆地土壤和水生沉积物中的总碳、氮和硫以及有机碳，以了解环境污染物的归宿和迁移（Branfireun，Macfie）。CHNS系统还将用于对浮游植物（Branfireun）和土壤生物（Lindo）进行创新性分析，这将为这些研究方案做出新的贡献。C，N，和S在植物组织和垃圾，土壤和沉积物，水生（浮游植物）和陆生（土壤生物）食物网的组成部分的分析将使我们能够支持基本的，前沿的研究控制生物多样性，微生物分解，汞转化跨越从生物分子到整个加拿大生态系统的生态系统尺度。
