Application and notes

Cyclohexane in GC quality (gas chromatography standard) is used as a high-purity solvent and reference standard in chromatographic analysis. Due to its exceptional purity and very low impurity content, it is suitable for precise qualitative and quantitative determinations in chemical, environmental, and industrial laboratories. The product should be stored in tightly closed containers, in a cool and well-ventilated place, away from ignition and light sources.
