D. Peak area. Peak area: It is the basic quantitative data provided by a chromatogram. The accuracy of peak area measurement directly affects the quantitative results, and different measurement methods are used for chromatographic peaks with various peak shapes. Generally, there are the following methods: peak height multiplied by half the peak width method, peak height multiplied by the average peak width method, normalization method, external standard method, and internal standard method.
