Developed for demanding processing applications, the Hplc Guard Columns (Analytical) Nucleodur ® C 18 Htec offer exceptional protection for your main HPLC column from contaminants. With a particle size of 1.8 μm and a column length of 4 mm, these guard columns provide optimal filtration capabilities, ensuring that chemical impurities do not reach the main column. Featuring a base deactivated (BDS), high density octadecyl (C 18 , ODS) modification, these fully porous particles (FPP) have a specific surface area of 340 m²/g, providing excellent separation efficiency. Additionally, they boast a pH stability range of 1.0-11.0 and a pressure stability of up to 900 bar, making them suitable for a wide variety of analytical applications. By using
