Test of the titration protocol with spectrophotometer for the Vitamin A (protocol titration)
I tested this protocol and tried to calibrate it. I used, like food sample, 1g of rice and I did 8 bottles with 8 different concentrations of pure vitamin A from 10 -1 to 10 -8 mg.ml-1.

Results :
We can just observe concentrations higher than 10-3mg.ml-1.
