TERAHERTZ SPECTROSCOPY FOR PREDICTING STABILITY OF AMORPHOUS DRUGS |
| 摘要 |
A method for characterising an amorphous material involves an evaluation of a rate of change with temperature of an interaction of the amorphous material with electromagnetic (EM) radiation. The interaction is at an energy of between 6.6×10−24 J and 6.6×10−21 J, which corresponds to EM radiation in the terahertz band, between 10 GHz and 10 THz. The rate of change of the interaction is evaluated in a temperature range below a glass transition temperature (Tg) of the amorphous material. The rate of change can then be compared with a predetermined value in order to characterise the amorphorphous material. An apparatus is provided to carry out the method, and the method can produce amorphous materials having desired properties, such as stability against crystallisation. |

1. A method for characterising an amorphous material, comprising the steps of:
evaluating a rate of change of an interaction of the amorphous material with electromagnetic (EM) radiation with temperature, at an energy corresponding to EM radiation of frequency between 10 GHz and 10 THz, in a temperature range below a glass transition temperature, Tg; and comparing the rate of change with a predetermined value. |
