(A) reference the date list,calculate the lower limit of detection (LOD=3) of
caffeine in concentration.
(B) calculate the concentrations of caffeine and theobromine in sample 1.
(C) calculate the reference of 10ppm theobromine spiked in sample 1.(SA-S1)
(D) calculate the theobromine concentrations of sample 2 by I.S. Calibration
method.(S2C)
