Water HPLC

Water used for HPLC applications undergoes further purification to remove impurities such as organic compounds, ions, and particulates that can interfere with chromatographic analysis. HPLC-grade water typically has a higher level of purity than ultrapure water used for other laboratory applications.

The purified water used as a mobile phase or solvent in HPLC is critical for obtaining accurate and reproducible results in analytical and preparative separations.

Some common uses of water in HPLC include:

• Preparation of mobile phases and buffer solutions
• Dilution of standards and samples
• Solvent for sample preparation and extraction
• Cleaning and maintenance of HPLC equipment
• Preparation of reagents and solutions for analytical chemistry applications
