This document introduces the advantages of Flash Chromatography, using the Varian 385-LC ELS and 971-FP to analyze samples containing a mixture of UV and non-UV active compounds.
This document highlights the advantages of dual detection in flash chromatography, specifically addressing the analysis of samples containing both UV and non-UV active compounds. It demonstrates how combining a UV detector with an Evaporative Light Scattering Detector (ELSD) prevents sample loss by detecting components invisible to UV light alone.
It allows the isolation of non-UV active compounds that would otherwise remain undetected by a UV detector alone.
