Spectroscopy

Spectroscopy is the set of analytical techniques that measure how matter absorbs, emits or scatters electromagnetic radiation, used to identify substances and quantify their concentrations. Instruments in this class span elemental analysis, molecular identification and optical rotation, each reading a different part of the spectrum. On Questpair, 777 spectroscopy listings are available from 19 verified suppliers and distributors across 12 countries. New, used and refurbished laboratory units are listed side by side, and 95 percent of the listings are used. Prices run from EUR 45 to EUR 201.000, a spread that reflects the gap between a bench polarimeter and a full ICP-MS platform. Spectroscopy underpins work in environmental testing, pharmaceutical quality control and materials characterisation.
