ASTM Committee E13 on Molecular Spectroscopy and Separation Science was formed in 1950. E13 meets twice a year, usually in March and October, with approximately 35 members attending three days of technical meetings. The committee, with current membership of 112, has jurisdiction of 62 standards, published in the Annual Book of ASTM Standards, Volume 03.06. These standards have and continue to play a preeminent role in techniques for ultra-violet and visible spectroscopy, infrared and near-infrared spectroscopy, molecular luminescence, nuclear magnetic resonance, Raman, chemometrics, and optical fibers, and gas and liquid chromatography.

In April 2000 Committee E19 on Chromatography merged with Committee E13 and is now designated as Subcommittee E13.19 on Chromatography.
