Calculate normalized concentrations

The normalized concentration of a compound refers to the concentration of the compound in relation to the sum of concentrations of all detected compounds.

The calculation depends on the status of the Apply correction factors to normalized concentrations check box. This check box is part of the calibration settings in the processing method.

If correction factors are applied, the Normalized concentration of a compound is calculated as follows, depending on the concentration calculation:

Or

If sample multipliers/dilution factors are not applied, the normalized concentration is calculated as:

where
C_N	Normalized concentration
M_comp	Compound multiplier, set in the processing method
A	Amount (including sample-specific compound multipliers)
M_sample	Sample multipliers, set in the injection list or sequence table
D_sample	Sample dilution factors, set in the injection list or sequence table
f	Normalization factor, defined in the processing method
