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 (limonene standard/carvone internal standard) versus the concentration of the limonene standards. A method of least square is employed to find the best line fitting all datapoint.- From the linear equation, calculation of the limonene concentration in the samplesolution can be achieved.
