Analysis of Anions in Wine Standard (VH-anion 4D)

Please use this column with suppressor type ion chromatography system.

WINE VH-anion 4D was used to quantify anions in wine standard. VH-anion 4D provides a rapid analysis without any influence from organic acid present in wine. This method using VH-anion 4D for the quantification of anions in wine was co-developed with Institute Heidger (Kesten, Germany). *The wine standard is prepared artificially that contains components that are generally present in wine and commercially available from an institute in Speyer, Germany.
