My Experiments 
VWR® n-Heptane (≥99%), supplied under the HiPerSolv CHROMANORM® brand, is a high-purity solvent specifically purified for high-performance liquid chromatography (HPLC) applications. Filtered through a 0.2 µm filter and packaged under nitrogen, this solvent offers excellent stability, low residue, and UV transparency, making it ideal for gradient HPLC and spectrophotometric applications.
n-Heptane is a non-polar hydrocarbon solvent widely used in chromatography, organic synthesis, and environmental analysis. Its defined impurity profile and spectral transparency ensure minimal baseline noise and high reproducibility in sensitive analytical workflows.
Key Features
- High Purity: ≥99% assay (anhydrous basis).
- Chromatography Grade: HiPerSolv CHROMANORM® for HPLC applications.
- Low Residue: Evaporation residue ≤10 ppm; water ≤100 ppm.
- Spectral Quality: Excellent transmittance and low absorbance in UV range.
- Filtered & Protected: 0.2 µm filtration and nitrogen packaging.
- Versatile Use: Solvent for chromatography, organic synthesis, and extraction.
Applications
- High-Performance Liquid Chromatography (HPLC): Non-polar solvent for gradient elution.
- Spectroscopy: UV-transparent solvent for spectrophotometric analysis.
- Organic Synthesis: Solvent in hydrocarbon-based reactions and separations.
- Sample Preparation: Extraction and purification of non-polar compounds.
- Environmental & Industrial Analysis: Reference solvent in testing protocols.
