Upload data
Use CSV, TXT, DAT, ASC, XY, or WDF files. For quick review, start with a single clean spectrum before testing mapping-style datasets.

RamanQuick guide
A practical reference for quick Raman analysis, custom peak fitting, and reproducible export.
Analyze
Quick analysis workflow
2
Choose workflow
Select the material workflow before upload when possible. Graphene, CNT, CNT RBM, MoS₂, and WS₂ use different peak windows and metrics.
3
Review metrics
Check peak position, FWHM, peak ratios, baseline status, and plots before exporting. Automated metrics are screening results, not final material assignment.
4
Export results
Export tables, figures, and processing logs so that the analysis can be reproduced later in Excel, Origin, Python, or other tools.
Fitting
Custom fitting terms
Center
Center is the initial Raman shift used to start the fit. The final fitted center can move unless the center window is restricted.
Center window
Use Free, ±3, ±5, ±10, or Lock to control how far the fitted center can move from the initial center. This is important for shoulder peaks.
Seed %
Seed % is only the starting height. Use 50 for weak shoulders, 100 for normal peaks, and 150 for strong main peaks. Final amplitude is fitted from data.
Area %
Area % is the fitted component area fraction. It helps compare overlapping components such as CNT G+/G− or deconvoluted graphene 2D peaks.
Model
Lorentzian is the safest default. Gaussian can represent inhomogeneous broadening, pseudo-Voigt is a mixed approximation, and BWF should be limited to clear asymmetric peaks.
Numerical fit
Stable, Check, and Unstable describe numerical behavior only. They do not prove material assignment or physical correctness.
Practical notes
Use Simple Baseline first for quick review.
Use Advanced Baseline only when the raw spectrum has strong curvature.
Use center windows to prevent components from drifting into the wrong peak.
Check residual shape, not only R².
Treat BWF and pseudo-Voigt fits as interpretation-sensitive choices.
Use Export Workbook to keep parameters, curves, processing log, and numerical fit summary together.
Scope
Interpretation limits
RamanQuick is intended for rapid review, component-level fitting support, and reproducible export. Numerical fitting quality does not prove material assignment, layer number, crystallinity, defect type, or metallic/semiconducting character. Final interpretation should be checked against sample context, laser wavelength, calibration, substrate signal, and experimental conditions.
