Characterization of the variation between batches of Fast-Flo lactose using low frequency dielectric spectroscopy.
The dielectric response of four batches of lactose has been measured over a frequency range of 10(4) to 10(-2) Hz. The spectra corresponding to three of the batches were identical, while the fourth showed a marked reduction in response. This particular batch has also been reported to exhibit longer disintegration times than the other three when formulated as a tablet. The potential use of dielectric spectroscopy as a means of screening batches of pharmaceutical materials is discussed.
