项目摘要

Project SummaryP.I. Chave, Alan (WHOI) Proposal #: 0527927P.I. Angel, Stanley (South Carolina) Proposal #: 0527910PROJECT TITLE: Oceanic Applications of Laser Induced Breakdown Spectroscopy: Laboratory ValidationProject SummaryThe goal of the proposed work is to investigate, characterize, and quantify a LIBS system in the laboratory for bulk aqueous solutions typical of the oceans at high pressure with some emphasis being placed on future applications at hydrothermal vent systems at mid-ocean ridges. The major products of the proposed work will be important instrumental parameters, in situ calibration standards, and fundamental, new information about LIBS plasmas at high pressure. This work will be critical to the future development of LIBS systems for in situ oceanic applications. The development of in situ chemical and biological sensors is a high priority in the ocean sciences, as is recognized in the reports from recent ocean sciences workshops. In particular, a realtime, non-invasive, multi-element chemical sensing capability which does not require sample preparation would be a significant advance over current oceanographic technology. The proposed work will support essential laboratory investigations required to implement such a sensor. Over the past two decades, a new spectroscopic technique called laser induced breakdown spectroscopy (LIBS) has been developed and is rapidly gaining favor for in situ field measurements in hostile environments. The LIBS technique utilizes a high power laser focused on a sample to create a plasma or "laser spark". A gated spectrometer covering part or all of the ultraviolet through near infrared range is used to capture the plasma spectrum. The plasma radiates both a continuum component which decays relatively rapidly and an emission line component which decays more slowly. The spectral line wavelengths and intensities obtained from plasma ablation can be compared with a standard atomic line reference and/or calibrated against samples of known makeup to determine the chemical composition of the sample. This relatively simple apparatus yields simultaneous sensitivity to virtually all elements in the parts-per-million or better range in solids, liquids, gases and aerosols. The approach is effectively non-invasive due to very small sampling regions and requires no sample preparation. It is also fast and is essentially a real-time measurement.
项目概要P.I. Chave,Alan(WHOI)提案编号:0527927P.I。Angel,Stanley(南卡罗来纳州)提案编号:0527910项目名称:激光诱导击穿光谱的海洋应用:实验室验证项目摘要拟议工作的目标是在实验室中研究、表征和量化LIBS系统,用于高压下海洋典型的散装水溶液,重点放在未来在大洋中脊热液喷口系统的应用上。拟议的工作的主要产品将是重要的仪器参数,现场校准标准,和基本的,新的信息LIBS等离子体在高压下。这项工作将是至关重要的LIBS系统在原位海洋应用的未来发展。正如最近海洋科学讲习班的报告所确认的那样,开发现场化学和生物传感器是海洋科学的一个高度优先事项。特别是,不需要样品制备的实时、非侵入性、多元素化学传感能力将是当前海洋学技术的重大进步。拟议的工作将支持必要的实验室调查,以实现这样的传感器。在过去的二十年里,一种新的光谱技术,称为激光诱导击穿光谱(LIBS)已经开发出来,并迅速获得青睐,在恶劣环境中的现场测量。LIBS技术利用聚焦在样品上的高功率激光来产生等离子体或“激光火花”。使用覆盖部分或全部紫外到近红外范围的选通光谱仪来捕获等离子体光谱。等离子体辐射相对快速衰减的连续分量和衰减更慢的发射线分量。从等离子体烧蚀获得的光谱线波长和强度可以与标准原子线参考进行比较和/或针对已知组成的样品进行校准,以确定样品的化学组成。这种相对简单的设备产生同时敏感性几乎所有元素的百万分之几或更好的范围内的固体,液体,气体和气溶胶。由于非常小的采样区域,该方法是有效的非侵入性的,并且不需要样品制备。它也很快,基本上是一种实时测量。
