AutoEvaluation

Smart Evaluation for Fast, Reproducible Results

AutoEvaluation is the first self-operating evaluation function that autonomously finds and evaluates effects in thermal analysis measurement curves of DSC, TGA, DIL/TMA and DMA types.

With one click in Proteus^® analysis or even automatically once a measurement has finished, caloric effects such as melting or CrystallizationCrystallization is the physical process of hardening during the formation and growth of crystals. During this process, heat of crystallization is released.crystallization peaks, Glass Transition TemperatureThe glass transition is one of the most important properties of amorphous and semi-crystalline materials, e.g., inorganic glasses, amorphous metals, polymers, pharmaceuticals and food ingredients, etc., and describes the temperature region where the mechanical properties of the materials change from hard and brittle to more soft, deformable or rubbery.glass transitions or mass changes are evaluated by means of intelligent mathematical algorithms. AutoEvaluation results are time-saving and user-independent, making them helpful for beginners and experienced users alike who can utilize the result as a second opinion.

Since several functions like “Polymer” or “SinteringSintering is a production process for forming a mechanically strong body out of a ceramic or metallic powder. Sintering Steps” exist, AutoEvaluation can be adapted to the particular application. The user can customize which evaluations done by AutoEvaluation should be displayed and which properties of these evaluations (like peak area, onset temperature, …) should be shown. Last but not least, the results of AutoEvaluation can be revised by the user – if desired.

`AutoEvaluation` in Practice

The `AutoEvaluation` function “Polymer Blend/Mixture” is applied to the second heating of a DSC measurement on the sample “PA6-ABS”.

After only one click, the Glass Transition TemperatureThe glass transition is one of the most important properties of amorphous and semi-crystalline materials, e.g., inorganic glasses, amorphous metals, polymers, pharmaceuticals and food ingredients, etc., and describes the temperature region where the mechanical properties of the materials change from hard and brittle to more soft, deformable or rubbery.glass transitions at around -79°C, 58°C and 110°C mid temperatures as well as the melting effect at 220°C peak temperatures are evaluated autonomously by `AutoEvaluation`.

`AutoEvaluation` for UV Curing

The `AutoEvaluation` function „UV-Curing” is applied to a DSC measurement where UV pulses were applied after every minute.

After only one click, all peak areas are evaluated, the correction peaks are considered for the corrected enthalpies, the total UV-Curing (Crosslinking Reactions)Literally translated, the term “crosslinking“ means “cross networking”. In the chemical context, it is used for reactions in which molecules are linked together by introducing covalent bonds and forming three-dimensional networks.curing enthalpy and the degree of Curing (Crosslinking Reactions)Literally translated, the term “crosslinking“ means “cross networking”. In the chemical context, it is used for reactions in which molecules are linked together by introducing covalent bonds and forming three-dimensional networks.curing are calculated (values and curve).

The `AutoEvaluation` function “Metal Melting Temperatures and EnthalpiesThe enthalpy of fusion of a substance, also known as latent heat, is a measure of the energy input, typically heat, which is necessary to convert a substance from solid to liquid state. The melting point of a substance is the temperature at which it changes state from solid (crystalline) to liquid (isotropic melt).Melting” is applied for the analysis of several DSC measurements on metal calibration standards at once.

After only one click, `AutoEvaluation` autonomically evaluated the onset temperature and calculated the corresponding enthalpy area (J/g) for each DSC curve, providing accurate results without further user input.

Customization to Fit Your Needs

The user defines which evaluations should be displayed and which properties of these evaluations (like peak area, onset temperature, …) should be shown
Evaluation thresholds can be adjusted by a sensitivity parameter
Offers editable results, giving users full control over refinement and reporting

Ideal Starting Point for Identify

AutoEvaluation also prepares your signals for further interpretation in Identify. By detecting relevant effects and structuring the data accordingly, it enables more precise material identification.
