Xylene for HPLC is a high‑purity, analytical‑grade solvent designed for HPLC and other chromatographic applications, offering low UV absorbance, consistent retention times, and reliable reproducibility.
🏭⚗️ Production
Purified through multi-stage distillation and advanced filtration to remove heavy metals, peroxides, and other organic impurities. Quality-controlled for low UV absorbance, minimal water content, and consistent batch performance. Packaged in airtight, solvent-resistant containers to prevent contamination and moisture uptake.
🔬 Properties
A clear, colorless to pale yellow liquid with a characteristic aromatic odor. Immiscible with water, fully miscible with most organic solvents. Exhibits moderate volatility, low viscosity, and excellent chemical stability. Hygroscopic under certain conditions; store in tightly sealed, cool, dry containers away from light.
🧪 Applications
Used as a solvent in HPLC mobile phases, sample preparation, and analytical standard solutions. Provides stable baselines, reproducible peak shapes, and consistent chromatographic performance in routine analyses, particularly in reversed-phase and normal-phase methods.
⚠️ Safety
Flammable and harmful if inhaled, ingested, or absorbed through skin. Vapors may irritate eyes and respiratory tract and cause CNS effects with prolonged exposure. Use appropriate PPE and handle in a well-ventilated area or fume hood. Keep away from heat, sparks, and strong oxidizers. Store in compatible, tightly closed containers.
