Chromatography

• Chromatography is a method for analyzing complex
  mixtures (such as ink) by separating them into
  the chemicals from which they are made.
• Chromatography is used to separate and identify
  all sorts of substances in police work. Drugs
  from narcotics to aspirin can be identified in
  urine and blood samples, often with the aid of
  chromatography.
