How do historians use chromatography?

Answer 1

Historians use chromatography to trace evidence and find out more about events in the past that might have occurred. For example if there was a letter written by a famous monarch or leader of which a historian would want to know more about, they would check the ink of the pen which answers to them of what pen they used, who had written it and how old the pen was when they used it and this answer can simply be found just by the method of chromatography which separates soluble substances from insoluble subtances.
