InertSustain C18 HPLC Column, 4.6 x 150 mm, 5 µm is used for general-purpose reversed-phase HPLC across quality-control, research, pharmaceutical, food, and related analytical workflows. The column contains fully porous, high-purity spherical silica with octadecyl C18 bonded groups and endcapping, packed as 5 µm particles in a 4.6 mm ID × 150 mm analytical format. The InertSustain C18 phase has a 100 Å pore size, 350 m²/g surface area, 14% carbon load, and USP L1 classification. Its recommended pH range is 1–10, and the phase is designed for chemical stability, low adsorption, and sharp peak shapes even for strongly ionic compounds. It can also operate with 100% aqueous mobile phase. Application data for this exact 5 µm, 150 × 4.6 mm configuration include fatty acids, indomethacin-related compounds, esomeprazole, and other small-molecule analyses, demonstrating its use as a versatile first-choice C18 phase for routine reversed-phase method development and established HPLC procedures.
