The CS 1521 HPLC System is complemented by UVTech high-performance chromatographic columns, designed to deliver superior stability, precision, and efficiency in every separation. Manufactured under strict GMP standards using imported, high-purity silica fillers, these columns ensure exceptional consistency and reproducibility. Their high specific surface area and elevated carbon content provide strong retention capacity and excellent sample loading capability, making them suitable for a wide range of analytical applications. The optimized bonding density of functional groups achieves a perfect balance between hydrophobicity and polarity, allowing precise control over compound interactions for improved selectivity. In addition, a novel endcapping technology minimizes residual silanol activity to undetectable levels, resulting in outstanding peak shapes—especially for basic compounds—and enhanced column durability. With these advanced design features, the UVTech columns integrated with the CS 1521 HPLC System guarantee stable, efficient, and reproducible separations, setting a new standard for high-quality chromatographic performance.
