HPLC analysis is a quantitative analysis method, and the content of the target substance in the sample needs to be determined by standard curve. Therefore, the standard curve and sample chromatogram should be presented at the same time in this paper, so that readers can understand the reliability and accuracy of the analysis results. In addition, relevant information such as analysis conditions and instrument parameters should be provided for readers to repeat experiments or compare analysis results. So hplc can't just put the sample chromatogram.

In addition to the standard curve and sample chromatogram, other relevant data and analysis results can be added in the paper, such as retention time, peak area, peak height and other parameters, as well as mass spectrometry analysis results.
