HanKing Liquid Chromatography Column

HanKing LC Column PurBridge / PurShell / Super / Pur The whole new product line is officially here! Leveraging three core technologies—high-purity spherical silica gel, organic hybridization, and core-shell surface modification—we’ve created high-quality columns that are wide pH tolerant, highly efficient, low-loss, and batch-stable. They cover all separation modes including reversed-phase, normal-phase, ion exchange, and HILIC, and are suitable for mainstream testing needs in pharmaceuticals, food, environment, chemicals, clinical, and life sciences. We’re dedicated to providing top-notch column options for analysis in different fields.

Key Highlights of the New Product
