Ultisil LP-Aq is a HPLC column designed to withstand 100%–0% aqueous environments. Featuring short-chain alkyl bonding technology, it can withstand strong acidic conditions, maintaining high stability of stationary phase even at low pH. It is particularly suitable for the separation of polar compounds in low to medium pH environments. Compared to the LP-C18 column, it offers distinct selectivity under the same chromatographic conditions.
