Must-have Ultisil Lp-c18, 5μm, 10×250mm, 300Å Tool [crkL4KRj]

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 LP-C18 column is a HPLC column designed to withstand 100% aqueous to 100% organic solvents. It features steric hindrance side-chain protection to shield hydroxyl groups and adopts a non-endcapped process. With strong spatial selectivity, it exhibits high orthogonality to conventional C18 columns, making it a suitable alternative for analytes that are difficult to separate on standard C18 columns. It demonstrates low stationary phase bleed under strongly acidic conditions, as an ideal baseline noise can be observed even when using an ELSD detector.
