Robbery on the Orient Express

White Powder

 A white powder has been used to identify fingerprints during the crime in order to find the murderer.The se eTwinning official was found unconscious in his cabine on the orient express. Some white powder was discovered by the turkish police on his bedside table.
So we are going to carry an experiment thanks to the TLC technique. The solvent used in the chromatography tank is a mixture of cyclohexane /butyl-acetate and methanoic acid.Finally, we used the UV lamp technique to reveal the compounds.
To find the nature of the white powder, we had to compare it with four dry white powder drugs.

-  A : BROMAZEPAM (anxiolytic)
-  B : STILNOX (sleeping pill)
-  C : ADVIL (ibuprofen)
-  D : ASPIRINE (aspirin)

After this experiment, we've concluded that the white powder was a mixture of BROMAZEPAM and STILNOX.
