Sodium Chloride for HPLC is a high-purity inorganic salt refined for analytical use, ensuring consistent performance in chromatographic buffers and aqueous mobile phases.
🏭⚗️ Production
Purified through recrystallization and filtration to remove trace metals, insoluble residues, and ionic contaminants. Quality-controlled for high purity, low conductivity variability, and compatibility with HPLC-grade solvents. Packaged in moisture-resistant, airtight containers to maintain stability.
🔬 Properties
A white, crystalline, odorless solid with high solubility in water and excellent chemical stability. Nonvolatile and nonflammable. Provides consistent ionic strength in buffer systems. Store in tightly sealed containers to prevent moisture absorption and caking.
🧪 Applications
Used in HPLC buffer preparation, ion-exchange chromatography, protein purification, and analytical method development requiring controlled ionic strength. Supports reproducible retention behavior and stable baselines in aqueous chromatographic systems.
⚠️ Safety
Generally low hazard but may cause mild eye or skin irritation as a solid or concentrated solution. Avoid inhalation of dust. Use gloves, goggles, and proper handling practices. Store in dry, tightly closed containers away from strong acids or reactive chemicals.
