A Unique, New Analysis Technique for Characterizing Materials... Modulated DSC
Nonreversing calorimetric data.
Conventional DSC calorimetric data.
Sinusoidal heating of material yields complex heat flow response. Deconvolution by discrete Fourier transform provides three data curves.
Reversing calorimetric data.

Modulated DSC (MDSC) is a new, patent-pending thermal analy sis technique which allows unique insight into the structure and behavior of materials. By subjecting sample materials to a sinusoidal, or modulated heating pro file rather than a linear heating profile, MDSC provides information which was previously unavailable. 109.0 Temperature (°C)
Unique analysis capabilities include: • Separation of reversing and nonreversing characteristics of thermal events. • Direct heat capacity measurement. • improved resolution of closely occurring and overlapping tran sitions. • Increased sensitivity for subtle transitions.
In addition, conventional DSC information is available from the same experiment. Modulated DSC is the latest in a 30 year history of innovations from TA Instruments, the world leader in thermal analysis instru mentation. MDSC complements the high sensitivity and wide temperature range of the TA Instruments Model DSC 2910 Differential Scanning Calorimeter, making it the most versatile thermal analysis instrument available.
