Reversed Phase Columns: Silica-based

TSKgel Super-ODS Stainless Steel Column, 2 μm, ID 2 mm x Length 5 cm

TSKgel Super-ODS columns are packed with monodispersed 2 µm spherical silica particles covalently bonded with octadecyl groups. The small particle size makes the Super series the highest efficiency reversed phase columns in the TSKgel product line. The monodispersed packing generates operational back pressures more typical of larger particles allowing the use of higher flow rates than other 2 micron packings.

TSKgel Super-ODS is an excellent choice for small peptides, amino acids, tryptic digests, nucleotides, pharmaceutical molecules and food/beverage samples.
