Kinetex 5 µm XB-C18 100 Å, LC Column 150 x 4.6 mm, Ea
Бренд: Phenomenex
Selectivity for Acidic Compounds
This unique C18 phase yields increased hydrogen bonding with hydrophobic selectivity‚ resulting in improved peak shape for basic compounds and increased retention of acidic compounds.
Complementary Core-Shell C18 Phases
Ultra-high performance columns like Kinetex will give you very narrow peaks, but without the right selectivities you are left with very narrow, overlapping peaks. The phases offered in the Kinetex column line are complementary to one another, so the spectrum of selectivity your separations require is covered.
