The problem of baseline in Origin software
***********************************************************************************************************************************************************************************************************************************************************************************************************************************************
There are two possibilities.
1) You have two equal length table with data. Then simply create new column and use "set column value" (by default Ctrl-Q) and write something like "Col(b)-Col(d) " where columns B and D intensity of Data and baseline.
2) You have only curves. Then use "Analysis > Mathematics > Simple Curve Math" (Note, that you should do this with your Graph window is active, not workbook)
If you are using origin higher version origin like 2016 and above Go to analysis-peak analyzer -create base line-select base line mode (three or four options are there) adjust the threshold, smoothing factor etc then click subtract and save you can also get the corrected data in the origin file

Lahoucine Atourki In OriginPro, the Peak Analyzer is capable of creating and subtracting baseline. There are various ways for baseline creation. You can generate baseline anchor points automatically or manually and then connect them with interpolation or fit them with a function, as discussed in the following video. In the case you want to further ask about it, please do comment on the specific video, I'll respond to it shortly. I have provided the practice file(s) here. Thanks
