Conclusion:

I can conlude from this lab practice that my hypothesis was partially correct. I learned the methods used in companies to separate matter and which materials are more suitable to which method. 

From the information gathered I can conclude that for evaporation the best materials are water and salt, for sedimentation water and soil, for decantation water and oil, for chromatography markers components and for filtration, water and coffee.

My errors in the hypothesis were filtration and sedimentation, which turned out to be water and soil for filtration, and water and sand for sedimentation.
