A controlled atmosphere microbalance system has been constructed for the measurement of moisture sorption in pharmaceutical materials. The system is automated, and the user can program arbitrary changes of relative humidity (RH) under computer contro

We report the results of an analysis of the OH stretching region of the vibrational spectrum of ice Ih. The model of ice Ih discussed in an earlier paper [J. Chem. Phys. 69, 3483 (1978)] is considerably improved in that a larger section of the proton

A simple general method for the determination of solvent residues in drugs is described. The procedure is based on wide-bore wall coated open tubular (WCOT) gas chromatographic analysis of bulk drug solutions. The use of wide-bore WCOT columns with c

The model developed in the preceding paper for the vibrational spectrum of ice Ih in the OH stretching region is extended to the description of the spectrum of amorphous solid water. The effects of structural disorder on the spectrum are explicitly c

The transmission spectra in the intramolecular stretching region have been measured for thin films of H2O and D2O polycrystalline ice Ih and amorphous solid water. The data have been reduced to obtain the complex refractive index in this region via a

Infrared absorption spectroscopy of very thin films (≈0.1 μm) of H 2 O(as) reveal that it is stable for of the order of minutes up to 160 K. This observation is used as a basis for discussion of the continuity of state between H 2 O(as) and liquid

The effect of temperature on drug release from meteneprost potassium vaginal suppositories was investigated using a dissolution test based on the USP I apparatus. Comparison of the dissolution results with the DSC melting behaviour revealed that drug

A novel application of microscopy-FTIR to monitor the dehydration of some hydrate compounds has been established, and some major instrumental parameters are identified. An application to erythromycin dihydrate indicated that the most notable spectral
