a Typical calibration curve for emission spectroscope(such as ICP or fluorescence) is linear at low analyte concentrations, when the x-axis is concentrations and the Y-axis is detector response. the detector response is directly proportional to the number of detected photons.
a) Explain why construction of a linear calibration curve for emission spectroscope does not require any logarithmic data manipulation(as is required for absorption spectroscope?
