Valentia Analytical – Analytical Lab Born in GMP

Analytical Testing

Ultra-High Performance Liquid Chromatography (UHPLC) is a core competence at Valentia Analytical enabling use of sub-2 micron particle columns to achieve maximal resolution.  This is in comparison to traditional high performance liquid chromatographic systems that could not.   That being said, methods may come in requiring the specific use of HPLC.  The specific system we have enables use of either mode, in UHPLC or HPLC.  Collective years of expertise have been forged with different chromatographic modes including reversed-phase, size-exclusion, ion-exchange, and affinity chromatography.
