The Federation of Analytical Chemistry and Spectroscopy Societies or FACSS  is a scientific society incorporated on June 28, 1972, with the goal of promoting research and education in analytical chemistry.  The organization combined the many smaller meetings of the individual societies into an annual meeting that includes all of analytical chemistry. The meetings are intended to provide a forum for scientists to address the development of analytical chemistry, chromatography, and spectroscopy.
The society's main activity is its annual conference held every fall.  These conference offer plenary sessions, workshops, job fairs, oral presentations, poster presentations, and conference networking events.  The conference was held internationally for the first time in 1999 when it was hosted in Vancouver, BC.  The annual conference is often discussed in the journal Applied Spectroscopy, Spectroscopy Magazine, and American Pharmaceutical Reviews.
At the 2011 FACSS Conference in Reno, NV, the FACSS organization changed the name of the annual conference to SciX. The first [http://scixconference.org/ SciX Conference] presented by FACSS was held in Kansas City, MO in 2012. The name change was discussed in Spectroscopy in fall 2011:
