AxisBenchTechniquesDSC analysis
DSCDifferential scanning calorimetry
DSC analysis: glass transitions, melting and enthalpy.
Find Tg, melting and crystallisation events with onset, peak and endset temperatures. Enthalpy and ΔCp appear only when the signal unit and heating rate support them, and every setting is saved with the result.
- Tg midpoint, onset, endset
- °C
- ΔCp at Tg
- J/(g·K), when traceable
- Peak onset, peak, endset
- °C
- Peak area, height, FWHM
- working units, °C
- Enthalpy
- J/g, when traceable
- Event direction
- endo or exo
Withheld values carry the reason, for example a missing heating rate.

01 · What it computes
From heat flow to characterised events.
Every transform is a named, parameterised step. Settings save as presets and run across a batch of curves.
Glass transition
Two constructions: step morphology for a single transition, or an ISO 11357-2-style two-tangent construction for several. Midpoint, onset and endset, with the tangent geometry stored.
Melting and crystallisation
Endotherms, exotherms or both, each with onset, peak and endset temperatures, area, height and FWHM. Templates for general DSC, polymer Tg and polymer melting and crystallisation.
Enthalpy and ΔCp
Reported in J/g and J/(g·K) only when the signal unit and heating rate are traceable. Otherwise they are withheld with the reason, never guessed.
Baselines and smoothing
AsLS, airPLS, ModPoly, IModPoly, SNIP, linear, rubberband, spline or a two-sided automatic baseline. Savitzky–Golay, moving-average or Gaussian smoothing and optional mass normalisation.
Deconvolution and dQ/dT
Split overlapping events into Gaussian, Lorentzian or pseudo-Voigt peaks, and preview the dQ/dT derivative beside the curve.
Kinetics
Runs at several heating rates go to Kissinger, Ozawa-Flynn-Wall, Kissinger-Akahira-Sunose, Friedman or Vyazovkin analysis for the activation energy.
02 · References
Context from the literature, not a curve library.
AxisBench does not match DSC curves against a reference library; the open libraries cover FTIR, Raman and XRD. For DSC, relevant papers are retrieved from OpenAlex and attached to the result, with their DOIs in the export.

Free
The Free plan shows the top literature result; Pro shows up to five. To identify the material behind a DSC event, add FTIR or XRD data to the same project and match it against the open libraries.
03 · Files and limits
What goes in, and what it does not claim.
Supported files
- CSV, TXT, TSV and ExcelColumns are mapped to temperature and signal at import, and quality warnings show before anything is computed.
- Instrument text exportsColumn headers from NETZSCH, TA Instruments and METTLER TOLEDO software exports are recognised at import.
- Heating rateRead from the file when present or entered by you. The project records which, and values that need it are withheld without one.
Limits
- Polarity is declared, not assumedIf the endo and exo direction of a file is unknown, event labels are withheld instead of guessed.
- No reference-curve matchingDSC results come from your curve. Identification comes from spectra or patterns in the same project.
- Kinetics needs several runsActivation energy needs the same event measured at more than one heating rate.
- ExportsTables as CSV or XLSX, figures as PNG and reports as DOCX or PDF. The whole project downloads as a file you can reopen later.
Other techniques in the same project
DSC, TGA, DTA, FTIR, Raman and XRD data live side by side in one AxisBench project. Full multi-technique reports come with Pro.
Characterise your next DSC curve.
The Free plan includes every technique and the full reference libraries, with 10 analyses a month (up to 3 a day). Pro removes the limits.
