High resolution separations at high loads and high flow rates. Wide range of selectivities. Reproducible quality. Excellent scalability. High chemical and physical stability. Low backpressure. SOURCE 15PHE 4.6/1NANA PE high capacity makes it an excellent choice for preparative hydrophobic interaction purifications at laboratory scale. In addition, its longer bed height provides increased resolution. The column is also useful for optimization studies during scaleup.
