Differential scanning calorimetry, for

NIRA provides a non-destructive alternative to differential scanning calorimetry for the determination of polymorphic forms of drugs, e.g. the polymorphic forms of caffeine. NIRA has also been used to determine optical purity. While the pure opposite enantiomers of a substance have identical NIR spectra, mixing two...

As we have seen above, Landau expansion coefficients a, B and C can be found from the measurements of order parameter S(7) and AH by different techniques, such as microscopy (for Tc), differential scanning calorimetry (for Tc, and AH), refractometry or NMR (for 5 ).

TA Instruments dynamic mechanical analyzers are used over a temperature range from -150 to 600°C (-238 to 1112°F) to measure deformations for shear, tension, compression, three-point bending, and dual/single cantilever [3]. They include an optical encoder. DMA instrumentation is more sensitive than differential scanning calorimetry for measuring smaller transition regions. The company s DSC instruments measure heat...

Mettler Toledo (Mettler) now markets the DSC 1 unit, but at the time that this instrumental brief was written, marketed only the DSC823 (its design is further discussed in Section 2.3, The Basics of Differential Scanning Calorimetry). For both units, Mettler now offers a two-sensor option based on a thermopile construction embedded in a chemically inert and corrosion resistant ceramic material. The sensors differ structurally in their design, although the primary difference is the number of thermocouples incorporated into each thermopile. The performance specifications are given in Table 2.8.

This chapter describes the basic principle, recent developments, and selected applications of some commonly used experimental techniques (i.e., optical microscopy, electron microscopy, atomic force microscopy, nuclear magnetic resonance, diffraction and scattering (X-ray, neutron, and light), and differential scanning calorimetry) for characterization of semicrystalline polymers. Many excellent reviews for each technique and their usage exist, and the listed references only represent the exem-...
