6. Results and DiscussionThe report must be the following information: - GC and MS condition- MS spectrum and Chromatograms standard solution and and unknows sample (including the data of peak area, peak height and retention time) - A calibration curve is prepared by plotting the ratio of peak area (limonenestandard/carvone internal standard) versus the concentration of the limonene standards. A method of least square is employed to find the best line fitting all data point.- From the linear equation, calculation of the limonene concentration in the sample solution can be achieved.
