Applications

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

General

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.
