Prevent degradation of labile compounds  Only a few simple preparation steps for cleaning validation


 With conventional solvent extraction, labile compounds may react with extraction solvents or could be oxidized and/or   Nexera UC can be applied to cleaning validation which is performed in the pharmaceutical industry to confirm that manufactuaring
 degraded.  equipment has been properly cleaned. Nexera UC automatically runs a series of steps from extraction to analysis, by only putting the
            sample swab in the extraction vessel. In conventional cleaning validation, the sample swab needs to be extracted with water, and
            then the extraction is analyzed by TOC. However, when a target compound is hydrophobic, swab extraction is performed with
            ethanol and TOC is not applicable. Nexera UC is capable of performing both types of cleaning validation.

 Analysis of biomarkers from dried blood spots (DBS)  Supercritical fluid extraction of trace additives in polymers


 Nexera UC can extract a trace amount of liquid samples. For biomarker validation, the preparation requires simply enclosing a   Polymer additives are widely used to prevent optical or thermal degradation, or to enhance functionalities. An example, Irganox 1010,

            and enclosing it in the extraction vessel, Nexera UC can detect labile or trace quantities of additives.
