An investigation of calibration methods for solution calorimetry

International Journal of Pharmaceutics, 2004
Solution calorimetry has been used in a number of varying applications within pharmaceutical research as a technique for the physical characterisation of pharmaceutical materials, such as quantifying small degrees of amorphous content, identifying polymorphs and investigating interactions between drugs and carbohydrates or proteins and carbohydrates.

Characterisation of polyethylene glycol solid dispersions using differential scanning calorimetry and solution calorimetry

International Journal of Pharmaceutics, 1991
Abstract Solid dispersions of nortriptyline HCl in a range of molecular weight PEG samples were manufactured using a low temperature fusion method, whereby the drug remained intact within the dispersion. The phase diagrams obtained using differential scanning calorimetry were monotectic in nature, suggesting that these diagrams represent systems ...

Novel sample container for solution calorimetry

Review of Scientific Instruments, 1979
A new design for calorimeter sample containers is described. The basic design is a hollow right cylinder with thin, glass membranes covering both ends. The membranes are intended to be broken out completely to release the sample contained within. The membranes are sealed to the container body with silicone rubber.

Solution Calorimetry Under Hydrothermal Conditions

Reviews in Mineralogy and Geochemistry, 2013
The first quantitative studies of the thermodynamics of hydrothermal solutions were made in 1903 by A.A. Noyes and W.D. Coolidge (1903), who used the change in conductance associated with ionization to measure the ionization constants of water and aqueous acids and bases up to about 300 °C at steam saturation.
