Results and Discussion Using model mixture C7-C40, calibration curves for all the analytes were established. A linear response between concentration (ranging from 0.2 to 50 µg/ml) and the intensity recorded in the positive mass spectrum under APCI-MS was observed. The linearity graphs for few analytes like C20, C29, C38 and C40 are shown in figures 3-56 to 3-59. Intens.
