In this case, you create a timed group with quantitation mode Reference. The specified times ranges of the timed group include the relevant not identified peaks. Optionally, a correction factor (Ref. correction) can be entered to multiply the response of the peak before the amount is calculated from the response factor of the reference compound.
In addition, quantified peaks must be excluded. By specifying the option Quantify each peak individually, amount and concentration of all not identified peaks are calculated using the curve reference.
