Concentration and mass%

The concentration is shown in the Concentration column in the injection results.

The calculation depends on the following settings (all settings are available in the General tab of the Compounds > Calibration node):

• Concentration and corrected amount calculation: with this setting you choose to use dilution factors either as a divisor or as another multiplier.

• Calculate mass %: calculate the concentration as a mass percentage (compound amount relative to sample amount).

With Calculate mass % cleared (this is the default setting):

Concentration = Amount * Multipliers * Dilution Factors

or

With Calculate mass % selected:

The concentration is calculated as a mass percentage (compound amount relative to sample amount).

or

where
Multipliers	Sample multpliers or compound multiplier
Dilution Factors	Sample dilution factors
Amount	Calculated amount (including sample-specific compound multipliers)

For more information on the calculation of multipliers and dilution factors, see Correction factors.
