Ultisil UHPLC LP-C18 is based on 1.8 µm high-purity silica and features steric hindrance side-chain protection to shield hydroxyl groups, along with non-end-capping process. With strong spatial selectivity and high orthogonality to conventional C18 columns, it serves as an alternative for compounds that are difficult to separate on standard C18 phases. Even under strong acidic conditions with an ELSD detector, it delivers an ideal baseline with minimal phase bleed, demonstrating excellent stability. This column is compatible with 100% aqueous to 100% organic mobile phases.
