Ultisil Plus C18, 5µm, 10×300mm, 130Å (1pcs/pk)

Welch preparative column uses the same packing materials as does analytical column, to ensure the best reproducibility of analysis and preparative scale. Special packing technique and stainless modular column tube ensure the stability of column bed. The theoretical plate number for 10 μm column is greater than 35000/m; for 5 μm column, it is greater than 75000/m, and the peak symmetry is around 0.95~1.20. Ultisil Plus C18 column has a lower specific surface area, slightly larger pore size, and lower carbon loading, resulting in weaker retention compared to XB-C18. The double end-capping process ensures excellent peak shape when analyzing acidic and basic polar compounds. Quantity: 1 pcs/pk
