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.
