TECHNIQUE #4 Dilution Method
Sample diluted with unreactive material of known m*
- Diluent may be either crystalline or amorphous but should not contain phases to be analysed
- Instead of measuring sample absorption, measurements of diluted and undiluted samples are made
- Diffraction from diluent must not interfere with analytical diffraction peak
- Diluent should not fluoresce, should be chemically inert, exist as fine powder and have mass absorption coefficient close to that of the sample
