Description

Technical Overview

ChromexC18 is a highly versatile reversed-phase column developed for routine and complex analytical separations. The stationary phase utilizes a densely bonded C18 ligand on high-purity spherical silica, providing strong hydrophobic retention and excellent chromatographic efficiency. Extensive end-capping minimizes secondary silanol interactions, resulting in symmetrical peak shapes and reliable reproducibility. The column is suitable for a broad range of pharmaceutical, environmental, and chemical analyses, especially where robust performance and long service life are required.
