Instrument: Spectrometer
A spectrometer is an optical instrument used to measure properties of light over a specific portion of the electromagnetic spectrum.
The speciation of particulate Fe in filter-bound hydrothermal plume particles was measured using micro-focused X-ray fluorescence mapping (u-XRF) and micro-focused Fe 1s X-ray absorption near edge structure (uXANES) spectroscopy at beamline 10.3.2 of the Advanced Light Source (ALS), Lawrence Berkeley National Laboratory, U.S.A
