The ZORBAX Diol guard cartridge is designed to deliver high-performance sample protection and extended column life for normal-phase and hydrophilic interaction liquid chromatography (HILIC) separations. Measuring 9.4 x 15 mm with a particle size of 6 micrometers, this cartridge effectively safeguards analytical columns from particulates and strongly retained contaminants, ensuring consistent peak shape and reliable results. Ideal for laboratories working with polar analytes such as carbohydrates, glycopeptides, and small polar pharmaceuticals, it supports method development and routine analyses in pharmaceutical, biochemical, and food testing research. The diol bonded phase allows for enhanced selectivity and reproducibility in HILIC and normal-phase applications, especially suitable for the separation of structurally similar compounds. This guard cartridge is conveniently supplied in a pack of two and is fully compatible with Agilent ZORBAX analytical columns, easily integrating with standard HPLC systems through appropriate guard cartridge hardware. Employing this protection device improves efficiency by reducing maintenance frequency and protecting the integrity of main columns, thus lowering operational costs. Its robust design and chemical stability make it suitable for a wide range of mobile phases, supporting diverse and demanding chromatographic workflows in both research and quality control environments.
