The PEAXACT Viewer is a feature-reduced but completely free version of the PEAXACT Desktop App for interactive viewing of UV/VIS/IR/Raman/NMR spectra and models. PEAXACT Viewer offers more professional spectra visualization than most spectrometer measurement programs and hence is a popular replacement on spectrometer PCs.

Visual Data Inspection

The Data Inspector is a graphical tool for the editing and visualization of spectra.
  • Organisation of big data (spectra and other measurements, e.g. concentrations, temperature, measurement time)
  • Explorative analysis with customizable 2D, 3D, and 4D (color-coded) diagrams
  • Principal Component Analysis (PCA)
  • Export of rendered and vector images (PNG, JPEG, TIFF, PDF, EPS, FIG)

Data Pretreatment

  • Immediate preview of all data manipulations
  • Region selection (global and local)
  • Resampling (thinning, re-calculation by interpolation)
  • Alignment
  • Baseline correction (offset, linear trend, rubber band)
  • Smoothing
  • 1st and 2nd derivatives
  • Standardization (maximum, area, SNV, peak)
  • NMR-specific: FID to spectrum, apodization, phase correction
