Product Overview
Hexanes for HPLC, containing approximately 95% n-hexane, are a high-purity solvent engineered for demanding chromatographic applications. This grade ensures minimal UV absorbance and low residual impurities, making it suitable for sensitive analytical techniques where solvent purity directly impacts results. The composition is optimized to reduce interference in detectors, providing consistent baseline stability during HPLC runs. Its narrow boiling range (68–70°C) ensures uniform evaporation, critical for reproducible separations. The solvent is stabilized to prevent peroxide formation, extending shelf life without compromising performance. Compatible with most stationary phases, it serves as an efficient mobile phase component for non-polar analyte separations. Packaged in amber glass bottles to prevent photodegradation, it maintains integrity during storage. The 95% n-hexane concentration balances cost-efficiency with high performance, offering a practical alternative to pure n-hexane for routine HPLC workflows. Its low water content (<0.01%) minimizes peak tailing in reverse-phase chromatography.
FAQs
1. What is the difference between HPLC-grade hexanes and reagent-grade hexanes?
HPLC-grade hexanes undergo additional purification to remove UV-absorbing impurities and have stricter specifications for residual solvents, making them suitable for chromatographic applications where baseline stability is critical.
2. Can this hexane mixture be used with normal-phase HPLC columns?
Yes, this 95% n-hexane blend is compatible with normal-phase silica columns and works effectively as a non-polar mobile phase component for separating polar compounds.
3. How should I store HPLC-grade hexanes to maintain purity?
Store in a tightly sealed amber glass bottle at room temperature, away from direct sunlight and ignition sources. Keep the container in a well-ventilated solvent cabinet to prevent vapor accumulation.
4. Is this hexane mixture suitable for GC-MS applications?
While primarily designed for HPLC, this grade can be used in GC-MS after verifying compatibility with your instrument’s inlet system and ensuring no residual stabilizers interfere with detection.
5. What alternatives exist if I need higher n-hexane purity?
For applications requiring >99% n-hexane, consider pure n-hexane (ACS or GC grade) or n-hexane for spectroscopy, though these may come at a higher cost.
