General description

Polyvinylpolypyrrolidone (Divergan) is used as an excipient to prepare samples for subsequent analysis steps. It has a wide range of applications, especially in the beverage industry. It is used to pre-treat samples such as juices with strong colors which would interfere with the analysis using MQuant or Reflectoquant test strips. For decolorization, the juices are mixed with the powder and filtrated afterwards. The resulting solution can then be used for the determination of e.g. ascorbic acid or HMF.
