HPLC Guard Columns (analytical) NUCLEOSHELL ® Biphenyl, 4 x 3 mm

Recommended for applications requiring controlled solvent behavior, such as liquid chromatography (LC, HPLC), pre-column systems like the Hplc Guard Columns (Analytical) Nucleoshell ® Biphenyl, 4 x 3 mm, play a crucial role in maintaining system integrity. Featuring a core-shell structure with superficially porous particles (SPP) and a particle size of 2.7 µm, these guard columns offer excellent pressure stability up to 600 bar. Their biphenylpropyl modified surface chemistry ensures reversed phase (RP) separation principles, making them suitable for a wide pH range of 1.5-8.5. With a specific surface area of 130 m²/g according to BET, these guard columns provide optimal solvent control while protecting the main HPLC column from contaminants, thereby extending
