Re: MS/FID TEMPLATE

You can save the template through the File > Save Template menu, then load the template to any chromatogram image by switching to the Template mode > Template > Load Template....

You can use Tools > Compare Images Side-by-Side to compare them interactively.

Re: The unit of Size I(50)

The Sec column in the figure already reports values in seconds.

Note that Size I is always a multiple of modulation period. It looks like the modulation period is 60s. If so, Size I values will be a multiple of 60s.

Re: MS/FID Simultaneous Analysis

You may identify peaks in MS data, create a template, and apply it to the FID data. If retention times are almost identical, template matching can be done with almost minimum distance thresholds. Note that retention times between MD and FID may not be always identical even with a splitter. We recent...

Re: The unit of Size I(50)

The CLIC column simply multiplies the value by 60. You may delete the *60 part and check what is reported. If it still reports a wrong value, please share the version of your software and a screenshot of the Blob Table.

Re: The unit of Size I(50)

If the values in minutes are to small to be displayed with the default 2 decimal places, you may right click on the Column Header "Size I(50)". A small window will pop up and allow you to increase the decimal places to be displayed. To display values in seconds, you may add a CLIC column w...
