Waters Guard Cartridge XSelect CSH Prep C18 5 um 30 x 10 mm Sealed Box

The Waters 186006899 Guard Cartridge is a specialized component designed to protect and extend the lifespan of a high-performance liquid chromatography (HPLC) column. This particular cartridge is packed with XSelect CSH Prep C18 stationary phase, which is a 5 µm particle size material optimized for preparative-scale separations. The cartridge has dimensions of 30 mm in length and 10 mm in diameter, a size suitable for protecting larger preparative columns. The CSH (Charged Surface Hybrid) technology of the stationary phase is a key feature, as it provides exceptional peak shape and resolution for basic compounds, even in low-ionic-strength mobile phases. The C18 chemistry is a standard reversed-phase chemistry, making it suitable for separating a broad range of nonpolar to moderately polar compounds. This Waters guard cartridge is a vital tool for maintaining the performance and reliability of chromatographic separations, particularly in preparative-scale workflows.
