Separation of Furfural and Guaiacol (DE-413)

Wine contains furfural and guaiacol. Furfural has butterscotch and caramel notes, and guaiacol has a charcoal, smoky note, both contribute to wine flavoring. In this application, furfural and guaiacol were analyzed using RSpak DE-413, a polymer-based reversed phase chromatography column.
