General description

Diethyl ether is a highly volatile, non-polar solvent with excellent solvating properties for lipophilic compounds. Its low UV absorbance and high purity make it suitable for analytical chromatography, particularly in GC, HPLC, and LC/MS workflows where solvent purity is critical for trace-level detection.

Application

Diethyl ether can be used as a solvent for sample extraction and injection in GC analysis of volatile and semi-volatile organic compounds due to its rapid evaporation and minimal residue.
