SPE Extraction Of Phenolic Compounds From Wine Using SiliaPrep™ C18 (17%)
This document describes a sample preparation method for the extraction of “phenolic compounds from wine” using SiliaPrep™ C18 (17 %) based on hydrophobic retention of the interfering wine components. Analysis of the sample can be done using GC-MS analytical technique.
This is a recommended general method using the SiliaPrep Reversed-Phase C18. Tips can be found for the choice of solvent that should be used to establish an SPE method development.
SiliaPrep C18 nec is a non-polar sorbent similar to SiliaPrep C18 but presents higher retention and polar selectivity for basic compounds. Unreacted surface OH's can be used for soft condition of catch and release purification of glucoronides for example.
SiliaPrep C18 is a non-polar sorbent used to extract acidic, neutral and acidic compounds from aqueous solutions, various organic compounds from water as well as drugs & metabolites from physiological fluids.
