chromatography

Definition

A laboratory technique for separating mixtures that's basically playing favorites with molecules based on how fast they travel. Scientists use it to figure out what's actually in that mystery substance—whether it's detecting doping in athletes or analyzing crime scene evidence. Think of it as a molecular obstacle course where different compounds finish at different times.

Example Usage

The forensic lab used chromatography to prove the 'vintage wine' was actually grocery store grape juice with food coloring.
