Product Overview
Cyclohexane, 99.8% pure and HPLC-grade, is a high-performance solvent designed for demanding chromatographic applications. This non-polar hydrocarbon exhibits exceptional purity with minimal UV absorbance, making it ideal for sensitive analytical techniques. Its low reactivity and excellent solvating properties ensure reliable performance in high-pressure liquid chromatography (HPLC) systems. The solvent’s narrow boiling range (80.7°C) and high evaporation rate contribute to efficient sample preparation and analysis. Manufactured under strict quality controls, this cyclohexane variant maintains consistent batch-to-batch performance with residual impurities kept below detectable limits. The product comes in sealed, amber glass bottles to prevent contamination and light-induced degradation. Its chemical stability and resistance to oxidation make it suitable for long-term storage under proper conditions. The 99.8% purity specification guarantees minimal interference in analytical results, while the HPLC grade certification ensures compliance with international standards for chromatographic solvents.
FAQs
1. What is the typical shelf life of HPLC-grade cyclohexane when stored properly?
When stored in tightly sealed original containers away from light and moisture at room temperature, this HPLC-grade cyclohexane maintains its specifications for at least 24 months from the date of manufacture. The amber glass packaging helps preserve its purity by minimizing light exposure.
2. How does the UV absorbance of this cyclohexane compare to standard laboratory grade?
This 99.8% HPLC-grade cyclohexane exhibits significantly lower UV absorbance than standard laboratory grades, particularly in the 200-250 nm range where many analytical detections occur. The purification process removes aromatic impurities that typically contribute to higher UV background in lower-grade solvents.
3. Can this cyclohexane be used as a mobile phase in normal phase HPLC systems?
Yes, this high-purity cyclohexane serves as an excellent mobile phase component in normal phase HPLC systems due to its non-polar nature and low viscosity. Its consistent quality ensures reproducible retention times and peak shapes when used in isocratic or gradient elution profiles.
4. What precautions should be taken when handling this solvent?
As with all organic solvents, handle this cyclohexane in a well-ventilated fume hood wearing appropriate personal protective equipment including chemical-resistant gloves and safety goggles. Avoid inhalation of vapors and skin contact, as it may cause irritation. Keep away from ignition sources due to its flammable nature.
5. How does the packaging prevent contamination during storage?
The solvent comes in amber glass bottles with PTFE-lined caps that provide an effective barrier against moisture and atmospheric contaminants. The glass construction prevents leaching of plasticizers that could occur with plastic containers, while the PTFE lining ensures chemical resistance and maintains the integrity of the seal.
