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.
