Using terahertz spectroscopy to provide supplemental information about lactose characteristics for optimization of DPI formulations.

Researchers have investigated numerous methods for determining amorphous content in lactose, all of which have limitations. One relatively new method that has attracted attention recently involves terahertz spectroscopy, which covers the spectral range between microwave and infrared, 40 Ghz to 4 Thz.
