COVID-19 Notice: The Chromatography Center is following a modified COVID-19 Standard Operating Procedure. Users must read the document prior to making an appointment to discuss or submit samples.

Updated June 15, 2020

Chromatography is a method for separation of components in a mixture, based on differences in attraction (retention) of these components for a mobile phase (a phase that flows) and stationary phase (a phase that is immobile). In gas chromatography (GC), the mobile phase is a gas (called the carrier gas; often helium) and the stationary phase is a solid or high boiling point liquid. In high pressure liquid chromatography (HPLC), the mobile phase is a liquid and the stationary phase is a solid.
