Metals Environmental and Terrestrial Analytical Laboratory (METAL)

The Metals, Environmental and Terrestrial Analytical Laboratory (METAL) is a shared-use facility available to all research staff, faculty, and students of all disciplines, within ASU, other universities, and commercial groups. Our laboratories house a collection of analytical instruments and preparative equipment for quantitative analysis supporting environmental and ecological research, among many other fields. Our instrumentation can support colorimetric/flow-injection, elemental analysis, surface area and porosity, gas phase carbon isotope analysis, ion chromatography, isotopic analysis of greenhouse gases, isotope-ratio mass spectrometry of light elements, and inductively coupled plasma mass spectrometry analyses of much of the periodic table. We specialize in measuring radiogenic and mass-dependent metal isotopes by multi-collector inductively-coupled plasma mass spectrometry.

Staff are committed to providing the tools necessary to meet the analytical needs of researchers while creating a valuable educational experience for users. Although most users prefer to receive individualized hands-on training enabling them to perform their own analyses, complete analytical services are also available. If you are have questions about laboratory capabilities, or a project you would like to discuss, please contact Gwyneth Gordon at
