Formula for Amount Calculation (Rel. to ISTD)

This function calculates the amount in an unknown sample by means of the ratio of the area to the Internal Standard. The prerequisite is that all peak areas of the sample have been determined including the area of the internal standard.

p	Indicates the peak number.
	Indicates the calibration function for the peak p that is calculated during the calibration. For more information, refer to Creating and Using Report Tables Calculating the Peak Variable "Amount".
	Indicates the determined area of peak p (for integration type = Area)
Resp.Fact.p	Indicates the scaling factor: The scaling factor can be specific for each peak; for example, to compensate the differing absorption behavior.
ISTD	Indicates the internal standard.
Dil.Fact.	Corresponds to the Dil.Fact. parameter from the sample list.
Weight (Sample Weight Factor)	Is a sample-specific factor that always refers to all peaks.
n	Indicates the sample number

The calculation of the calibration curve is the precondition for amount calculation. For information about how the calibration curve is calculated, refer to Theory of Calibration Evaluation with Various Standard Methods.
