Remarks

Cyclohexane in GC quality (for gas chromatography) is a highly pure solvent for analytical applications, especially for the precise determination of trace impurities by GC. Due to its low residue after evaporation and very low content of water and interfering compounds, it is used in quality control, environmental, and trace analysis laboratories. The product should be stored in tightly closed containers, away from ignition sources and light.
