Analysis of Pigments and Extenders

The separated pigment (extender) is usually used as starting material for analysis (see Section 10.1.1). If quantitative separation is not possible (e.g., in emulsion paints) the inorganic pigment (extender) fraction can be obtained by ashing the nonvolatile fraction for further details see [10.5]. 

For many inorganic and organic substances. X-ray diffraction spectra recorded on powdered materials are commercially available on a data carrier (CD-ROM) [10.38].
