Product Overview
n-Heptane (99% purity) is a high-performance solvent specifically designed for HPLC (High-Performance Liquid Chromatography) applications. Its ultra-low impurity profile ensures consistent and reliable chromatographic separations, making it ideal for demanding analytical workflows. The solvent’s non-polar nature and narrow boiling range (98.4°C) enhance selectivity in hydrocarbon analysis, while its low UV absorbance minimizes interference in UV-detection methods. Manufactured under stringent quality controls, this HPLC-grade n-Heptane adheres to strict specifications for residual moisture, particulate matter, and trace contaminants, guaranteeing reproducibility in sensitive assays. Its stability under standard lab conditions further extends shelf life without compromising performance. Whether used as a mobile phase component or for sample preparation, this solvent delivers precision and efficiency for critical separations.
FAQs
1. What is the shelf life of HPLC-grade n-Heptane?
When stored in a tightly sealed container away from direct sunlight and moisture, HPLC-grade n-Heptane maintains its purity for up to 24 months from the date of manufacture. Always check the label for the exact expiration date.
2. Is this n-Heptane compatible with standard HPLC columns?
Yes, this HPLC-grade n-Heptane is compatible with most reversed-phase and normal-phase HPLC columns, including C18, silica, and cyanopropyl stationary phases. However, verify column specifications for solvent restrictions.
3. Are there lower-purity alternatives available for general lab use?
For non-HPLC applications, technical-grade or reagent-grade n-Heptane (typically 95-97% purity) is available. These alternatives are cost-effective but may contain impurities unsuitable for sensitive analyses.
4. How should n-Heptane be stored to prevent contamination?
Store the solvent in a cool, well-ventilated area, away from oxidizing agents, open flames, and ignition sources. Use a dedicated solvent cabinet or flammable liquid storage to minimize exposure to air and humidity.
5. Can this solvent be used for GC (Gas Chromatography) applications?
While primarily formulated for HPLC, this high-purity n-Heptane can also serve as a solvent or standard in GC applications, provided the system is compatible with its boiling point and chemical properties.
