5) Assume that you are a researcher in R\&D laboratory and you have an unknown sample for HPLC analysis. Total concentration of unknown sample is 550ppm. After your chromatographic run, you get results and Figure 1 represent your chromatogram result. According to Table 1, please define the peaks which shown in Figure 1. (30 points) Table 1. Name of analytes and retention times of standard After defining the peaks, please calculate the concentration of analytes using the below Table. Please calculate the percentages of each analytes in the unknown sample. Table 2. Equations and peak areas of analytes
