The lab then used this internal standard calibration data to analyze a plant sample prepared with the same amount of added internal standard. The analysis of this plant sample yielded a VX peak area of 25,345 and an internal standard peak area of 28,523.
��
Set up an internal standard calibration curve, plot it, show all regression calculations, and determine the amount of VX in the plant sample.
