    The paper explores the use of differential scanning calorimetry (DSC) and temperature modulated differential scanning calorimetry (TM DSC) to study α- and β- processes in amorphous sucrose and trehalose. The real part of the complex heat capacity is evaluated at the frequencies, f, from 5 to 20mHz. β-relaxations were studied by annealing glassy samples at different temperatures and subsequently heating at different rates in a differential scanning calorimeter.
    The potential compatabilities of various commonly used excipients with Indomethacin (IMC) were compared using differential scanning calorimetry (DSC). Some agents were found to have no solid state interaction whereas others showed major changes in the thermograms signifying possible interactions in the solid state. The results show that DSC can be employed in preliminary preformulation studies for the evaluation of solid state interactions as an aid to excipient selection.

    Differential scanning calorimetry has been used to investigate the heat of fusion (ΔHf=7·12 kcal per g mol) and true melting temperature (T0=422·4°K) of pure cholesterol (99·5 mole%). In addition to analysis of the thermograph by an existing method a new and more rapid procedure has been used for evaluation of the purity of substances. Evidence is given that differential scanning calorimetry measurements at low scanning rates (0·5,1° min−1), followed by correction for premelting, are essential for estimation of ΔHf of substances not ultra-pure, at higher scanning rates large errors result. The entropy of fusion of cholesterol is similar to that of the simpler cholesteryl esters.
