Eau

Water is ultrapure, deionized, and filtered to remove particulates, organic contaminants, and ions that could interfere with chromatographic analysis. It is characterized by low UV absorbance and high resistivity, making it suitable for use as a mobile phase component or sample diluent in HPLC and LC-MS applications.

Water can be used:

• As the aqueous component in binary or ternary solvent systems for separating polar and non-polar analytes.
• To dissolve or dilute samples prior to injection into the HPLC system, ensuring compatibility with the mobile phase and minimizing baseline noise.
