Uses for chromatography
Uses for Chromatography. separated and what are the processes used to complete these separations?

  • Paints, inks dyes and food colourings are often mixtures of substances that have different colours. These can be separated using paper chromatography.

  • Can detect very small amounts of harmful pesticides in foods

  • Detect drugs in urine

  • Separate complex chemicals found in cells of living things

  • Check composition and purity of chemicals used in industry

  • Used to make and purify chemicals by manufacturers of medicines.
