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.
