Waters, 186001344, Atlantis dC18 Column, 100Å, 5 µm, 4.6 mm X 150 mm, 1/pk

Atlantis dC18 Column, 100Å, 5 µm, 4.6 mm X 150 mm, 1/pk is used for reversed-phase HPLC analysis when improved retention of polar compounds and reliable operation with highly aqueous mobile phases are needed. The column uses a silica substrate with difunctionally bonded dC18 ligands and an endcapped surface. Its spherical 5 µm particles have a 100 Å pore size and a 12% carbon load. The analytical format is 4.6 mm inner diameter × 150 mm, with a maximum pressure of 6000 psi (415 bar) and a supported pH range of 3–7. The dC18 phase is optimized for high-aqueous conditions, including 100% water, and is designed to resist dewetting while maintaining useful retention for polar analytes. This makes it suitable for routine reversed-phase methods that must handle compounds with a wide polarity range without switching to a different chromatographic mode. The 5 µm particle format and standard 4.6 mm bore make the column compatible with conventional HPLC workflows, including legacy methods, routine quality testing, and method development where polar retention and aqueous mobile-phase compatibility are more important than ultra-high-pressure performance.
