Chromatogram window in EA Extension

The Result Table in the EA Extension Chromatogram window has two additional columns performing EA calculations. These columns are:

Carbon Amount Ratio

Displays the ratio of the carbon amount to the given row's element amount.

Carbon Amount Ratio = Carbon Amount / Element (C,H,N,...) Amount

Carbon Response Ratio

Displays the ratio of the given row's element response to the carbon peak response, be it Area or Height. The column is hidden in the default desktop.

Carbon Response Ratio = Element (C,H,N,... ) Response / Carbon Response

 

The Sample Weight value, which is defined per chromatogram and typically comes from the sequence (where it may have been measured using controlled analytical balances), is displayed in the Common for All Signals section of the Results tab and also appears as a column in the Summary Table, showing the value for each open chromatogram.
