Altura HPLC columns from Agilent deliver exceptional bio-inert performance and long-term stability for the most demanding liquid chromatography applications. Incorporating Agilent’s Ultra Inert coating, these columns eliminate metal–analyte interactions that cause peak tailing, signal loss, and inconsistent recovery. The result is a fully inert flow path that enables sharper peaks, higher sensitivity, and more accurate quantitation for metal-sensitive compounds. With rapid equilibration, superior reproducibility, and durable performance, Altura columns ensure reliable results across LC and LC/MS workflows.

The Altura Poroshell HPH-C18 is a high-performance reversed phase HPLC column designed for use under elevated pH conditions. It features Ultra Inert stainless steel hardware and a 1.9 µm superficially porous particle for outstanding efficiency and sensitivity. The hybrid particle design provides exceptional mechanical and chemical stability, supporting a pH range of 3–11 and temperatures up to 65 °C. Ideal for high-pH LC methods, this column offers improved selectivity, consistent peak shape, and extended lifetime – reducing downtime and replacement costs. The Altura Poroshell HPH-C18 delivers robust, reproducible separations and high-resolution performance, making it the optimal choice for laboratories requiring stability in high-pH workflows.
