Fully automated on-line sample preparation and

            analysis of target compounds



            Nexera UC on-line SFE-SFC is a revolutionary system that combines on-line SFE and SFC in a single flow path (patented technology).
            Target compounds are extracted from solid samples and then automatically transferred to SFC/ MS so that no human
            intervention is required. The Nexera UC on-line SFE-SFC system reduces the time for pretreatment of samples and
            acquires highly accurate data.




                  Comparison of QuEChERS sample preparation and Nexera UC in the analysis of residual pesticides


            A typical sample preparation takes 35 minutes and requires several manual steps. With Nexera UC, the same sample can be ready
            for on-line SFE/SFC analysis in as little as five minutes with only a few simple sample preparation steps.
