Agilent Raman Spectroscopy’s proprietary technologies use novel variants of Raman spectroscopy. Their instruments can rapidly and accurately identify materials hidden inside objects or through opaque barriers such as plastic, coloured glass, paper and skin, or can measure the concentrations of materials in mixtures, with a high degree of accuracy. Agilent Raman Spectroscopy is formerly known as Cobalt Light Systems and is part of Agilent.
