Product Name – n-Hexane 99% For HPLC & UV Spectroscopy Quantity/Pack Size – 1000 ml, 2500 ml Form – Liquid Grade – HPLC & UV Spectroscopy Application – Solvent for chromatography, extraction, and spectroscopic analysis

Product Overview

n-Hexane 99% is a high-purity, non-polar solvent specifically designed for HPLC (High-Performance Liquid Chromatography) and UV spectroscopy applications. Its exceptional purity ensures minimal interference in analytical procedures, making it a preferred choice for laboratories requiring precise and reproducible results. The solvent exhibits low UV absorbance, which is critical for UV-Vis spectroscopy, where even trace impurities can distort readings. Its high volatility allows for rapid evaporation without leaving residues, ensuring clean sample preparation and instrument longevity. The 99% purity grade guarantees consistency in retention times and peak resolution during chromatographic separations. Additionally, its chemical stability and low reactivity make it suitable for extracting non-polar compounds from complex matrices. This grade of n-Hexane undergoes rigorous quality control to meet international standards, ensuring batch-to-batch reliability. Whether used as a mobile phase in HPLC or a blank solvent in UV spectroscopy, its performance remains uncompromised, delivering accurate and reliable data for critical lab workflows.

FAQs

1. What is the shelf life of n-Hexane 99% when stored properly?

When stored in a tightly sealed container away from heat, moisture, and direct sunlight, n-Hexane 99% typically retains its purity for up to 24 months from the date of manufacture. Always check the label for the exact expiry date.

2. Can this grade of n-Hexane be used for gas chromatography (GC) applications?

While primarily formulated for HPLC and UV spectroscopy, n-Hexane 99% can also be used in GC as a solvent or diluent, provided the application does not require ultra-low residue or specialized GC-grade solvents. For GC-MS, a dedicated GC-grade solvent is recommended.

3. Is this n-Hexane compatible with plastic containers for storage?

n-Hexane can degrade certain plastics over time, leading to contamination. For long-term storage, use glass containers with PTFE-lined caps. If plastic must be used, opt for HDPE or PTFE-coated bottles designed for organic solvents.

4. What precautions should be taken while handling n-Hexane in the lab?

n-Hexane is highly flammable and should be handled in a well-ventilated fume hood, away from ignition sources. Wear appropriate PPE, including nitrile gloves and safety goggles, to avoid skin and eye contact. Avoid inhalation, as prolonged exposure may cause dizziness or nausea.

5. How does the purity of this n-Hexane compare to technical-grade hexane?

This 99% HPLC/UV-grade n-Hexane undergoes additional distillation and purification steps to remove impurities like aromatics, sulfur compounds, and water, which are present in technical-grade hexane. The result is a solvent with superior transparency in UV ranges and minimal chromatographic interference.
