Mac-Mod Evosphere C18/AR, 100 Å, 5um, 10 x 10 mm Monodisperse Fully Porous Guard Cartridge
Evosphere UHPLC and HPLC columns are 100 A Monodispersed Fully Porous Silica-based columns designed to combine the benefits of Fully Porous and Core-Shell particle technology into an improved particle design and morphology that brings cutting-edge loading capacity to ultra-high-resolution particle columns. The Monodispersed Particles provide similar efficiency to Core-Shell products when comparing them directly via particle size matching and significantly increase loadability which allows ultra-high resolution analytical separations to scale to preparative separations for isolation work if needed. The bonded phase chemistries are exciting as well to maximize selectivity with novel C12 bonded phase, 2 multi-modal C18/AR, and C18/PFP bonded phases, an extended and stabilized phenyl funtionality in the Diphenyl bonded phase, a polar endcapped AQUA phase, a Phenyl-Hexyl phase, a propyl PFP phase and the RP18-Amide bonded phases which is great for doing bases at low pH.
Sepax Technologies Inc Sepax HPLC Column Antibodix WCX, NP3, Guard cartridge with holder, 4 x 10 mm
Antibodix columns are specially designed for high resolution, high efficiency and high recovery separations of antibodies. The packing support is composed of a rigid, spherical, highly cross-linked poly(styrene divinylbenzene) (PS/DVB) non-porous bead. The non-porous resin has particle size 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. On the top of the hydrophilic layer, weak cation-exchange functional groups are attached via a proprietary chemistry, resulting in high capacity ion-exchange layer.
