Duva
Deep Ultra Violet Analyser
GC-UV
Gas Chromatography – Ultra Violet with spectral of short wave lengths of light as a chemical analytical method was first discovered by Dr. Kaye in 1962. From early 1980-ies Dr. Verner Lagesson and licentiate Lagesson-Andrasko have been developing the technology and methods. From 2010 a new technical generation started to emerge, developed by a dedicated team to meet the highest up to date standards and requirements.
