Advanced Materials Technology HALO 90 Å PCS Phenyl-Hexyl, 2.7um, 3.0 mm x 50 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.
Waters Corp Nova-Pak C18 Guard-Pak Insert, 60Å, 4 µm, 10/pk
Nova-Pak C18 columns are general purpose, silica-based, reversed-phase C18 columns that are based on 4 µm particle technology. Compared to a 5 µm column, Nova-Pak columns offer higher resolution, more efficient separations, and faster chromatography.
Waters Corp DeltaPak C18 Radial-Pak Guard, 300Å, 15 µm, 25 mm X 10 mm, 2/pk
Delta-Pak packings, ideal for the separation of peptides, proteins, and natural products, are based on a highly stable, bonded, endcapped 5µm or 15µm spherical silica. Delta-Pak is available in two different pore sizes (100Å and 300Å) with either C4 or C18 bonded phase. Delta-Pak packings are available in different cartridge and column configurations, providing consistent and predictable scale-up capabilities for milligram-to-gram scale purification. Also, by having the same chemistry available on a high-efficiency 5µm particle, you can easily check the purity of your fractions.

Sepax Technologies Inc Sepax HPLC Column Proteomix WAX, NP10, 2 x 10 mm
Proteomix ion-exchange phases have been innovatively developed for achieving high ion-exchange capacity, a breakthrough technology for non-porous resins. Proteomix packing support is composed of a rigid, spherical, highly cross-linked poly(styrene divinylbenzene) (PS/DVB) non-porous bead with particle size selections of 1.7, 3, 5 and 10 µm. The PS/DVB resin surface is grafted with a highly hydrophilic, neutral polymer thin layer with the thickness in the range of nanometer. The hydrophobic PS/DVB resin surface is totally covered by a hydrophilic coating that eliminates non-specific bindings with biological analytes, leading to high efficiency and high recovery separations for biological molecules.
Sepax Technologies Inc Sepax HPLC Column HP-C18, 5 µm, 120 Å, 4 x 10 mm
