... are discussed—DTA and XRD. With the DTA method, the exothermic peak that accompanies slag devitrification at high temperatures is measured and converted in slag percentages. The method’s description includes preparation of standards, calibration curve, and calculation of slag content of an unknown cement sample...

...NL Redman-Furey; ML Dicks; J Godlweski; DC Vaughn; WJ Collins TGA-DTA plays a central role in the strategy outlined for early evaluation of the solid state forms available to pharmaceutical new chemical entities. At this early stage of development, compound and time are typically at a premium, so...

...NL Redman-Furey; ML Dicks; J Godlweski; DC Vaughn; WJ Collins TGA-DTA plays a central role in the strategy outlined for early evaluation of the solid state forms available to pharmaceutical new chemical entities. Understanding of the solid state forms becomes more difficult when individual samples...
