Produced to ensure dependable processing results, pre-column systems for high-performance liquid chromatography (HPLC) like the Hplc Guard Columns (Analytical) Nucleodur ® NH 2 -RP, 3 μm, 4 x 2 mm, are essential components that safeguard the longevity of your primary HPLC column. Featuring a 2 mm internal diameter and 4 mm length, these guard columns are designed with fully porous particles (FPP) and an aminopropyl (NH 2 ) surface chemistry, ensuring multi-mode (RP and NP), reversed phase (RP) separation principles. With a pore size of 110 Å, a specific surface area of 340 m²/g, and a temperature stability of up to 60 °C, these guard columns provide optimal performance while maintaining
