Since propylene glycol is a liquid, Gas Chromatography-Mass Spectrometry is one of the method to detect propylene glycol. Analyte: Propylene Glycol

Gas Chromatography-Mass Spectrometry

An analytical method that combine features of gas-liquid chromatography and mass spectrometry to identity different known substances within a test sample and identify trace elements in materials that were previously thought to have disintegrated beyond identification.

High-Performance Liquid Chromatography (HPLC)

A technique in analytic chemistry used to separate the components in a mixture to identify and quantify each component.  It relies on pumps to pass a pressurized liquid solvent containing the sample mixture through a column filled with a solid absorbent material. Each component in the sample would then interacts slightly differently with the adsorbent material, causing different flow rates for the different components and hence leading to the separation of the components as they elute out the column.
