Engineering Research Equipment: X-Ray Fluorescence Spectrometer for a Rapid in Situ Aquatic Survey System

9700004 Noakes该赠款为购买多色散X射线荧光（XRF）光谱仪提供资金，该光谱仪将被纳入CAIS设计的船上系统，用于快速数据收集，分析和绘制水生环境。 连续沉积物取样和分析系统（CS）使用安装在拖曳雪橇上的潜水泵将连续的表层沉积物流输送到船上处理器。 可以使用XRF光谱立即分析样品的元素成分。 多色散仪器将波长色散系统和能量色散系统集成在一个单元中，通过提高可靠性和降低可测量的最低检测水平，提供沉积物元素成分的上级分析结果。 ***

9700004 Noakes This grant provides funds for the purchase of a multi- dispersive x-ray fluorescence (XRF) spectrometer that will be incorporated into a CAIS-designed shipboard system for rapid data collection, analysis, and mapping in aquatic environments. The Continuous Sediment Sampling and Analysis System, or CS, uses a submersible pump mounted on a towed sled to deliver a continuous stream of surface sediments to a shipboard processor. Samples can be immediately analyzed for elemental constituents using XRF spectroscopy. The multi-dispersive instrument incorporates both wavelength- dispersive and energy-dispersive systems in one unit, providing superior analytical results for sediment elemental constituents by improving reliability and reducing the minimum detection levels that can be measured. ***
