Use of multiple heating rate DSC and modulated temperature DSC to detect and analyze temperature-time-independent transitions in materials

Differential scanning calorimetry is a widely used method for the observati on of phase transitions in plastics. However, it often requires a level of skill that is beyond many of today's operators, who must be familiar with m any analytical techniques. The new approach to DSC described in this paper provides a powerful approach to complex thermal analysis even in the hands of the routine operator.
