HPLC Guard Columns and Cartridges
Advanced Materials Technology HALO 90 Å PCS Phenyl-Hexyl, 2.7um, 4.6 mm x 250 mm
Built upon proven Fused-Core technology for speed and efficiency, the HALO PCS column products are positively charged surface chemistries designed to deliver improved peak shapes for basic compounds observed with standard Phenyl-Hexyl chemistry. Ideal for use with low ionic strength mobile phases, HALO PCS maintains peak symmetry at higher loading capacities and provides alternate selectivities from Phenyl-Hexyl bonded phases. The columns are optimized to deliver performance for reproducible, high efficiency LC and LCMS separations.
