Answer:The kit includes one guard cartridge, a stand-alone holder, tubing, nuts and ferrules.
Ascentis® C18 Supelguard Guard Cartridge is designed for protecting reversed-phase C18 analytical columns from strongly retained contaminants and particulate load before they reach the main separation bed. This configuration is a guard cartridge kit with a 2 cm × 4 mm stainless-steel cartridge packed with 3 µm fully porous high-purity silica carrying an endcapped C18 phase. The stationary phase has 100 Å pores, 450 m²/g surface area and 25% carbon loading and is suitable for USP L1 methods. It supports HPLC and LC-MS use across pH 2–8 at temperatures up to 70 °C. The kit includes one guard cartridge, a stand-alone holder, tubing, nuts and ferrules, allowing the protective cartridge to be installed directly upstream of a compatible analytical column. The chemistry matches Ascentis C18 separations, making it useful for preserving analytical-column performance while retaining comparable reversed-phase selectivity at the head of the system.
