Use proper PPE (nitrile gloves and eye protection) when handling acids.Percuoco, D. Houpt Reviewer(s): Revised by: Management Approval: Revised: 376 March 2018 Previous Versions: V1.1 6 Jan 2014 (IODP-II), V1.0 7 August 2013 Domain: Chemistry System: ICP-AES Elemental Analysis Keywords: ICP, dissolved metals.
![]() The Agilent For Your Safety Users Guide details additional safety information. Become acquainted with these resources before proceeding through this user guide. Johnston and Jeff Ryan for their help and advice in fleshing out the solids methodology in this User Guide, as originally presented in the Exp. IODP Proceedings Methods chapter. ![]() The JRSO also thanks all of the many other geochemists who have provided help and advice over the many years of elemental analysis on the JOIDES Resolution. Dissolved sample flows through an introduction system in which the component molecules are desolvated, atomized and excited within an argon plasma. Portions of these photons are directed through an optical chamber and ultimately fall upon a diffraction grating where they are reflected at angles determined by their wavelengths, separating them, like a prism, into discrete spectral orders. The photons impinge on an accurately aligned CCD or CMOS detector chip, and thus are mapped to a 2-D pixel array. A given element concentration is determined by locating its spectra within the array (i.e. The Agilent 5110 ICP-OES is used for routine shipboard measurement of interstitial water and hard rock matrices. The Waters method allow for simultaneous determination of major and minor dissolved elements. The Hard Rock method yields elements making up the major oxides, minor elements, and several trace metals that surpass the limits of detection. ICP-OES analytical results are heavily matrix dependent, thus the suite of elemental analytes may be altered on a per expedition basis depending upon the material collected. Safety Considerations Before conducting an analysis for the first time, consult the Agilent Technologies Agilent 5100 and 5110 ICP-OES Users Guide and For Your Safety Users Guide for a detailed review of safety issues. Listed below is a succinct overview of several important safety issues which are flagged, when appropriate, within the text: Ensure there is adequate storage space and ventilation for high-pressure argon gas bottles. Bottles must be secured to a rack, and the racks must be secured to the ship. The steel cap for each bottle must be in place whenever the bottles are not connected to the gas manifold. Use Swagelok Snoop Liquid Leak Detector to ensure proper seals at argon bottle and gas manifold connections. Samples and standards are made up in dilute solutions of concentrated nitric acid.
