Temperature-modulated DSC techniques (TMDSC) are widely used in thermal analysis in industrial and university research laboratories to separate overlapping temperature-dependent and time-dependent thermal effects.
Methods used up until now have overlaid the isothermal temperature or heating ramp with a (usually) sinusoidal temperature modulation of just one frequency (single frequency method). In contrast,TOPEM® , the new advanced multi-frequency temperature-modulation technique, uses a large number of different frequencies (multi-frequency approach).
The basic idea of TOPEM®is to overlay the isothermal or ramped temperature with a time series of stochastic (random) temperature pulses of different duration.
The advantages of TOPEM® are:
At the same time, TOPEM® allows the quasi-static frequency-independent heat capacity to be measured.

Once you have registered for the Webinar, you will receive all the information you need about TOPEM®. After the presentation in English, you have the opportunity to discuss points of interest directly with METTLER TOLEDO applications specialists.
- One measurement – simultaneous measurement of sample properties as a function of time and temperature over a large frequency range
- cp determination from the pulse response – very accurate determination of the quasi-static heat capacity
- Simultaneous high sensitivity and high resolution – allows the measurement of low energy transitions and/or close-lying temperature- dependent effects
- Separation of reversing and non-reversing processes – heat capacities can be determined with unrivaled quality even if the effects overlap
- Simplifies interpretation – frequency-dependent effects (e.g. glass transitions) can be easily distinguished from frequency-independent effects (e.g. loss of moisture)
- Extended PEM technique – eliminates instrumental influences and extends the measurable frequency range
At the same time, TOPEM® allows the quasi-static frequency-independent heat capacity to be measured.
