1. According to various retention values of chromatographic peaks, qualitative analysis can be carried out.
2. According to the area and height of chromatographic peak, quantitative analysis can be carried out.
3. According to the retention value of chromatographic peak and its area width, the separation efficiency of chromatographic column and the separation degree of two adjacent chromatographic peaks can be evaluated.
4. According to the distance between two chromatographic peaks, we can evaluate whether the choice of stationary phase or mobile phase is appropriate.
