| titleOfInvention | Method for the qualitative and quantitative infrared spectroscopic determination of mineral building materials |
| abstract | An infrared spectroscopic process is used to make a quantitative and qualitative determination of the mineral constituents of the building materials. The novelty is that: (a) the representative sample is removed from the material; (b) the sample is homogenised and a fraction is ground to powder in a tungsten carbide mill for 14-16 min; (c) the particles are mixed with a calcium bromide embedding agent suitable for IR spectroscopy and pressed to form a plug for use as a test sample; (d) the test sample is inserted in an FTIR spectrometer in which the reflected light provides an absorbent spectrum for evaluation; (e) the spectrum is analysed , the signal/noise ratio is determined in those parts of the spectrum at which peaks are anticipated; (f) the peak separation provides a determination of the basic curve and the selection of the basic curve process; (g) a quantitative determination of the peak is undertaken in accordance with the spectral quality and nature of the mixture; and (h) the nature and respective portions of the ingredients is declared. |
