The use of XRPD and ATR-FTIR in the screening of three component co-amorphous systems created via a melt- quench method

Multiple three-component co-amorphous systems have been created via a melt- quench method. This has been confirmed by a single glass transition in the individual DSC traces and then reinforced by X-ray diffraction data, which show an absence of crystalline material. ATR-FTIR has also been used to show a change in bonding vibrations between the physical mixtures and co-amorphous samples. The change in bonding vibrations indicates different molecular interactions within the co-amorphous materials.
