Analytical spectroscopy is a mature field, but advances in instrumentation, measurement, and sample preparation techniques continue to be made. Much recent development has seen a heavy emphasis toward techniques and instrumentation that allow for noninvasive, in situ, and in vivo procedures while still retaining a high degree of sensitivity. This article will review some of this progress over the past two to three years across five major spectroscopic fields: Raman, laser-induced breakdown spectroscopy, X-ray fluorescence, infrared, and inductively coupled plasma techniques.
