In case of single-level calibration, the response factor is simply the ratio of the calibration point response and amount. If Include origin and Force origin are switched off, a warning is emitted.
The response factor RF is defined as a ratio of response and amount or vice versa (see RF definition). To calculate the RF, the application uses the compound amount of the calibration sample and the corresponding response of the calibration sample.
The formula for the single-level calibration calculation of the ESTD results depends on the type of response that you have set in the processing method:
Amount = Peak Area / RF
or:
Amount = Peak Height / RF
