Product Overview
n-Heptane HPLC is a high-purity, non-polar solvent specifically designed for high-performance liquid chromatography (HPLC) and other demanding laboratory applications. With a minimum purity of 99%, this solvent ensures reliable and reproducible results in analytical procedures where low UV absorbance and minimal impurities are critical. Its narrow boiling range (98.4°C) and excellent solvent properties make it ideal for separating non-polar compounds in chromatographic systems. The solvent is distilled under strict quality controls to eliminate trace contaminants, ensuring compatibility with sensitive detectors like UV, RI, and MS. Its low viscosity and volatility further enhance efficiency in sample preparation and instrument performance. n-Heptane HPLC is also widely used as a reference standard in calibration processes due to its consistent composition and stability. The solvent is packaged in amber glass bottles to prevent photodegradation, preserving its integrity during storage and handling. For laboratories requiring ultra-pure solvents, this grade of n-Heptane delivers the precision and reliability needed for advanced analytical techniques.
FAQs
1. What is the difference between HPLC-grade and reagent-grade n-Heptane?
HPLC-grade n-Heptane undergoes additional purification steps to remove UV-absorbing impurities, making it suitable for sensitive chromatographic applications, while reagent-grade may contain trace contaminants that interfere with detection.
2. Can this n-Heptane be used with GC-MS systems?
Yes, the high purity and low residue profile of this HPLC-grade n-Heptane make it compatible with GC-MS systems, though it’s primarily optimized for HPLC applications.
3. How should n-Heptane HPLC be stored to maintain its purity?
Store the solvent in a tightly sealed container, away from direct sunlight and moisture, at room temperature (15–25°C). Use amber glass bottles to prevent light-induced degradation.
4. Is this solvent suitable for use in UV-Vis spectroscopy?
Yes, its low UV absorbance in the 190–400 nm range makes it ideal for UV-Vis spectroscopy, particularly for baseline corrections and solvent blanks.
5. What alternatives exist if n-Heptane HPLC is unavailable?
For similar applications, consider n-Hexane HPLC or Isooctane HPLC, though their polarity and elution properties may vary slightly, requiring method adjustments.
