A JEOL USA electron probe microanalyzer has been installed at the Southeastern North Carolina Regional Microanalytical and Imaging Center to expand research and educational opportunities for students, faculty and the regional industry. The state-of-the-art facility was opened in 2009 as a joint collaboration between Fayetteville State University and the University of North Carolina at Pembroke. The microprobe can be accessed by students at both universities to advance environmental, geological and forensic science research.

A charged elementary particle of an atom; the term is most commonly used in reference to the negatively charged particle called a negatron. Its mass at rest is me = 9.109558 x 10-31 kg, its charge is 1.6021917 x 10-19 C, and its spin quantum number is 1/2. Its positive counterpart is called a positron, and possesses the same characteristics, except for the reversal of the charge.
An instrument that produces an intense, tightly focused beam of ions to stimulate emissions from a minute section of a sample undergoing spectroscopic analysis. The ion beams found in microprobes are used in mass spectrometry; where laser light is used in absorption spectroscopy; and x-rays are used in crystal spectroscopy.
Acronym for profile resolution obtained by excitation. In its simplest form, probe involves the overlap of two counter-propagating laser pulses of appropriate wavelength, such that one pulse selectively populates a given excited state of the species of interest while the other measures the increase in absorption due to the increase in the degree of excitation.
