Product Overview
Cyclohexane 99.9% is a high-purity, non-polar solvent optimized for high-performance liquid chromatography (HPLC) and UV-visible spectroscopy. This analytical-grade reagent is meticulously distilled to eliminate trace impurities, ensuring minimal UV absorbance and consistent baseline stability in chromatographic separations. Its low refractive index and excellent transparency in the UV range make it ideal for spectroscopic applications requiring precise optical clarity. The solvent’s narrow boiling point range (80.7°C) guarantees reproducible retention times in HPLC systems, while its chemical inertness prevents unwanted reactions with analytes. Packaged under nitrogen to prevent oxidation, this cyclohexane maintains its purity throughout storage. Its compatibility with common HPLC mobile phases and UV cuvettes further enhances its versatility in laboratory workflows. The 99.9% purity specification is verified through gas chromatography, with residual water content maintained below 0.005% to prevent interference in sensitive analyses.
FAQs
1. What is the maximum UV cutoff wavelength for this cyclohexane?
The UV cutoff for this 99.9% cyclohexane is ≤200 nm, making it suitable for most UV-Vis spectroscopy applications without significant absorbance interference.
2. Can this cyclohexane be used with reverse-phase HPLC columns?
Yes, it is fully compatible with C18 and other reverse-phase columns, though its non-polar nature makes it more commonly used in normal-phase chromatography systems.
3. How does the packaging prevent contamination during storage?
The solvent is packaged in amber glass bottles with PTFE-lined caps under nitrogen atmosphere to block moisture and oxygen ingress, preserving purity.
4. What’s the typical shelf life when stored properly?
When stored in original sealed containers at room temperature away from direct sunlight, the shelf life is 24 months from the date of manufacture.
5. Are there any stabilizers added to this cyclohexane?
No stabilizers are added, as the high purity (99.9%) is maintained through rigorous distillation and packaging processes without requiring additives.
