Key words: stationary
phase, mobile phase, chromatogram, mixture, laboratory, analytical chromatography...
This research work is based on chromatography.
This is a technique for the separation of mixtures through which it’s possible
to separate all components. The mixture we want to separate is put in the stationary
phase, meanwhile the mobile phase, which is a gas or a liquid, sweeps the mixture along with
different velocities, causing this way the separation. We can see the different
components thanks to the marks in the chromatogram.
Practice in the laboratory consists of
investigating witch dissolvent or mobile phase is better in our laboratory. Once know the dissolvent (eter the
petrol-acetona) we could separate various samples of vegetable pigments with
chromatography of paper and thin layer chromatography.
Chromatography is
used in all kind of science ambits being also useful to separate between
samples of vegetable pigments to the investigation of a soft-drink component or
for toxics elements in blood.
