詳細

General description

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.

Application

WX0004P-1 is packaged in poly coated glass bottles
Expiration Dated

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.

Packaging

M-Bottle for Solvents
As a global leader in lab reagents, we are constantly looking for new ways to optimize the safety of our products. The newly developed 4L solvent bottle design features advanced sealing technology that eliminates leaks to make the handling of solvents safer and more convenient than ever before.
