Achieves the highest levels of sensitivity due to split-less injection of the entire volume of eluent into the mass spectrometer Technological background The innovative Nexera UC system offers a supplementary chromatographic technique to conventional LC and GC analysis that enables separation of an even wider range of non- to very polar analytes. Automated extraction and chromatography is achieved using a mobile phase of supercritical carbon dioxide which exhibits the solubility of a liquid with the diffusivity of a gas.
