Crafted to support technical production environments, the Hplc Guard Columns (Preparative) Nucleodur ® Sioh, 10 x 16 Mm are designed as pre-columns that protect your main HPLC column from contamination. With a length of 10mm and an inner diameter of 16mm, they are ideal for technical applications where longer column lifetimes are essential. Featuring unmodified high purity silica gel (SiOH) as its surface chemistry, these guard columns offer multi-mode (NP and RP) separation principles, making them suitable for both normal phase (NP) and reversed phase (RP) separations. They also boast a pore size of 110 Å, a specific surface area of 340 m²/g, and a pressure stability of up to 400 bar, ensuring robust performance under various conditions.
