FAQ
What Factors Can Affect The Separation Of Pigments? There are many factors that can affect the separation of pigments. These include solubility, the size of the particles, and the pigment's attractiveness to the paper-based upon the pigment's chemical structure. How Do Impurities Affect Gas Chromatography?
