Description

General description

This pre-blended solvent eliminates time-consuming mobile phase preparation as well as lost sample information and instrument downtime caused by impure mobile phases. For consistent baselines and minimal background noise, these blends are prepared with ultra-pure acids such as formic acid.

Application

Designed for use with HPLC and LC-MS.

Packaging
