    For the first time ever, it showcases complete automation of SFE sample pre-treatment and analysis by liquid or supercritical fluid chromatography. The Nexera UC system is designed to fulfil the measurement requirements of a wide range of applications including: monitoring of pesticides in food products; investigation of biomarkers; additives in polymers; drug discovery in pharmaceuticals and biopharmaceuticals, environmental controls and cleaning validation, to name just a few.

    Increasing speed and efficiency while reducing the risk of human error in the analytical workflow The Nexera UC online SFE-SFC approach eliminates the need for tedious, manual sample pretreatment. All samples are extracted under light-shielding, anaerobic conditions, enabling highly reproducible analysis even of unstable compounds that are easily oxidized or degraded using a conventional liquid extraction method.
