comatografia is incorrectly written, and should be written as "chromatography" being its meaning:
comotografia = Cromatografiala chromatography is a physical separation method for the characterization of complex mixtures, which applies to all branches of science. It is a set of techniques based on the principle of selective retention, which aims to separate components of a mixture, allowing to identify and determine the amounts of these components. Subtle differences in the coefficient of partition of the compounds resulting in a differential retention on the stationary phase and therefore an effective separation according to the retention times of each component of the mixture.
