Résumé :
I have chosen to make my training period in England at Tilbury in order to discover the English way of life and to improve my English too.
I worked under the supervision of Andy Waterman and Tom Cripps and we worked together, in collaboration with Renzi Virginie, on a method to determine the percentage of starch in fibre.
The test was very large, about 400 samples, in order to calibrate the method. The precision required was high and it was very important for the company that all tests had to be made with the same technician in order to have good and homogeneous results.
We used a polarimeter which is used to measure the optical activity exhibited by inorganic and organic compounds.
