Acquisition of Automated Carbon/Nitrogen Elemental Analyzer

海洋研究中碳和氮的元素分析跨越了生物学、化学和地质学的学科，涉及多种样品类型，包括实验室培养的微生物(例如细菌、浮游植物、原生动物)和浮游动物生物量、水柱颗粒、沉积物捕集材料、表层微层样品和海底岩心样品。对于世界卫生组织的科学家来说，这种测量在浮游植物和细菌营养动态、初级生产力、水柱营养循环、微生物食物链动力学、水柱颗粒转化和通量、热液喷口生物学和化学、石油地球化学、气-海交换过程和海底-水柱相互作用的研究中发挥着关键作用。我们正在请求一个新的CHN元素分析仪，将由来自4个不同部门的WHOI科学家组成的不同小组共享。

Elemental analyses of carbon and nitrogen in oceanographic research crosses the disciplines of biology, chemistry, and geology and involves a diverse array of sample types including laboratory-grown microbial (e.g. bacteria, phytoplankton, protozoa) and zooplankton biomass, water column particulates, sediment trap material, surface microlayer samples, and benthic core samples. For scientists at WHOI such measurements play pivotal roles in studies on phytoplankton and bacterial nutrient dynamics, primary production, water column nutrient cycling, microbial food chain dynamics, water column particulate transformations and fluxes, hydrothermal vent biology and chemistry, petroleum geochemistry, air-sea exchange processes, and benthic-water column interactions. We are requesting a new CHN elemental analyzer that will be shared by a diverse group of WHOI scientists from 4 different departments.
