Recommended for applications requiring controlled solvent behavior, such as hydrophilic interaction chromatography (HILIC), the Hplc Guard Columns (Analytical) Nucleodur ® Hilic offer excellent protection for your main HPLC column. With a particle size of 3 μm, fully porous particles (FPP), and a pore size of 110 Å, these guard columns provide a specific surface area of 340 m²/g, ensuring efficient filtration and minimal backpressure. The ammonium – sulfonic acid (zwitterionic) modified surface chemistry offers stable performance across a wide pH range of 2.0-8.5, while the pressure stability of up to 600 bar ensures durability under high-performance conditions. The columns' temperature stability of 60°C further enhances their versatility for various analyt
