Write a short article about how chromatography is used in every day life. I've been unsuccessful finding much information on exactly how and why it is used for any specific task, ie RNA fingerprinting, blood testing, airport security, etc. If anyone has any detailed information on exactly how chromatography is applied in any of the ways above - or any other applications of it, for that matter - it would be much appreciated.
