NGA Amounts

The NGA Results contains some of the columns from the standard Result Table, but it also contains additional columns specific for NGA Extension.

Chromatogram window - NGA Results

Compound Name

If the chromatogram contains calibrated peaks or groups, the names are shown in Compound Name column. The table contains compounds from all signals of the chromatogram.

Signal

Displays the Signal whereon the Compound was detected.

Amount [Mole %]

This column shows the same data as the Amount column in the Result Table (Results tab in the Chromatogram window). This columns is informational and isn't important in the NGA.

Amount [Molar %]

Contains mole fractions (in percent) or some other fraction type specified in the settings per all signals. The fractions are normalized amounts so that the total amount is 100%. If a compound isn't linked to a Name in Norm (for more details see also chapter Link Table), its mole fraction will be set to zero.

The table can contain a virtual compound Water. This one is added when you select Wet Basis in the NGA Settings.

The "minus" icon means, that the Compound Name from the NGA Results was not found in the selected norm and it's not needed for calculations.

The "question" icon means, that the Compound Name cannot be found neither in the Norms Table nor in the Link Table. Click the Edit Link Tableā€¦ button and in the desired Link Table dialog link the compound name with requested compound name in norm. This icon may appears in such situation, when the Compound Name is in the NGA Results twice or more times. This is caused mostly when you use one calibrated peak in more then one signal in the Calibration window. Since the NGA Calculations are performed on all signal in the Chromatogram, each Compound can be set in one signal only, see the chapter "Calibration".
