2.41 2D Peak Analysis(Pro)


The App 2D Peak Analysis is used to perform 2d peak fitting, and integrate each peak fitted data.


  1. Download the sample file and unzip the file to get one Origin matrix book file(.ogmu file).
  2. Start this tutorial with the app 2D Peak Analysis installed. If you have not installed this app, please click Add Apps button in Apps Gallery to open App Center to search and install the app.
