Acquisition of a Graphite Furnace Atomic Absorption Spectrometer.

摘要

The atomic spectroscopy facility which serves the School of Ocean and Earth Sciences and Technology (SOEST) and the marine minerals community comprises three spectrometers. These are: (1) a Perkin Elmer 603 flame/hydride/furnace atomic absorption/emission spectrometer (FAAS), (2) A limon Labs PS1 inductively coupled plasma atomic emission spectrometer (ICP/AES) and (3) a Perkin Elmer Z5100PC state-of-the-science dedicated graphite furnace atomic absorption spectrometer (GFAAS). The latter was purchased through funding provided by the Marine Minerals Technology Center (MMTC) and matching funds from the Hawaii Institute of Geophysics (HIG). The systems allow ultra-trace elemental analysis under near total computer control in a variety of sample matrices ranging from fresh to seawater, brines metalliferous sediments, and raw, beneficiated and processed ores as well as their process streams. Referral is made to previous technical progress reports for further details of the instrumentation and its capabilities. The facility which has only a half-time state-funded technician depends primarily on research grants for support; hence, it operates on a recharge schedule. Users are charged an hourly fee based on the type of service provided by the facility.
