Engineering and Mining Experiment Station (EMES)
The longest-running core research facility at the South Dakota School of Mines and Technology, the Engineering and Mining Experiment Station (EMES) has provided analytical services to the public and private sectors since 1903. Founded by the South Dakota Legislature more than a century ago, what was then named the Mining Experiment Station performed assays and experiments on the treatment of ores and other mineral products.
Today, the EMES acts as a centralized facility for multi-user instrumentation supporting research, training, and the acquisition of new equipment. It works to acquire, manage, and maintain analytical instrumentation to support faculty research, graduate and undergraduate research, academic programs, other academic and governmental organizations, and the private sector. The center also trains students on the proper use of the equipment.
Analytical methods in use include a wide variety of classical and advanced instrumental techniques for the characterization and testing of minerals, ores, raw materials, and manufactured products. The EMES operates and maintains facilities and oversees training in electron microscopy (scanning and transmission electron microscopes), X-ray diffraction, atomic absorption spectroscopy, inductively coupled plasma mass spectrometry, carbon/sulfur and hydrogen/nitrogen/oxygen analyses, as well as field-portable instrumentation for visible and near infrared spectroscopy, Raman spectrometry, and X-ray fluorescence spectrometry. In 2012, the EMES added a high-resolution 3D X-ray microscope facility.
The EMES also works closely with other departments on campus, which house additional instruments, including a gas chromatograph-mass spectrometer, a laser particle size analyzer, Raman and FT-IR spectrometers, and scanning tunneling and atomic force microscopes.
The EMES supports a wide range of clients that wish to utilize equipment and elicit support. From 2004-10, the center supported 20 programs and 50 faculty members at the School of Mines; nine state universities and government entities; 39 state industries; 28 national and international industries; and two federal government entities.
