March 1st 2017Analytical 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 towards techniques and instrumentation that allow for non-invasive, 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, LIBS, XRF, IR, and ICP techniques.
