Product Overview
This 99.5% pure isopropanol is specifically formulated for high-performance liquid chromatography (HPLC) applications, ensuring exceptional purity and consistency. The solvent undergoes rigorous purification processes to eliminate UV-absorbing impurities, water content, and residual contaminants that could interfere with analytical results. Its low evaporation residue makes it particularly suitable for gradient elution techniques where baseline stability is critical. The product’s controlled acidity and alkalinity levels prevent column degradation while maintaining peak resolution. Packaged in high-density polyethylene containers to prevent solvent absorption and contamination, this isopropanol maintains its specified purity throughout its shelf life. The solvent’s refractive index and density are carefully monitored to meet international pharmacopeia standards, ensuring batch-to-batch reliability for reproducible results in demanding laboratory environments.
FAQs
1. What distinguishes HPLC-grade isopropanol from regular isopropyl alcohol?
HPLC-grade isopropanol undergoes additional purification steps to remove UV-absorbing compounds, metals, and other impurities that could interfere with chromatographic analysis. It has stricter specifications for water content, acidity, and evaporation residue compared to technical or reagent grades.
2. Can this isopropanol be used with all HPLC column types?
The solvent is compatible with most reversed-phase columns including C18, C8, and phenyl phases. However, for normal phase chromatography or specialized columns like HILIC, you may need to verify compatibility with the column manufacturer’s recommendations.
3. What is the typical shelf life of unopened HPLC-grade isopropanol?
When stored in its original, tightly sealed container at room temperature away from direct sunlight, the product maintains its specified purity for at least 24 months from the date of manufacture.
4. How should I dispose of unused isopropanol?
Follow your institution’s chemical waste disposal protocols. Typically, small quantities can be evaporated in a fume hood, while larger volumes should be collected as flammable liquid waste for professional disposal.
5. Does this isopropanol contain any stabilizers or additives?
This HPLC-grade isopropanol is free from added stabilizers, denaturants, or preservatives that could potentially interfere with chromatographic analysis or sample preparation.
