Sepax Technologies Inc Sepax HPLC Column PolyRP-1000, Guard cartridge with holder, 5 µm, 2 x 10 mm
GP-C8 phase is synthesized with monomeric and fully endcapped chemistry. The uniform octyl stationary phase allows high efficiency with lower hydrophobicity compared to ODS phase. GP-C8 phase is suitable for separating compounds with a wide range of hydrophobicity. It is highly recommended for separating the compounds which are too strongly retained on C18 phases.
Sepax Technologies Inc Sepax HPLC Column GP-C18, Guard cartridge with holder, 3 µm, 120 Å, 4 x 10 mm
GP-C18 uses full coverage bonded silica packing, which provides exceptionally high stability. The unique mono-functional bonding chemistry of GP-C18 avoids the formation of multiple C18 layers. Such uniform stationary phase allows the separation to achieve high selectivity and high efficiency.
Sepax Technologies Inc Sepax HPLC Column HPLC Guard Cartridge (No Holder), Proteomix SAX, NP5, 4 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
HP-C18 uses full coverage bonded silica packing, which provides high stability. Compatible with 100% aqueous mobile phase and suitable for separations of acidic, neutral and basic organic compounds, as well as pharmaceuticals and peptides. ODS monolayer formed by special bonding chemistry does not collapse in pure aqueous solution.
Sepax Technologies Inc Sepax HPLC Column BR-C18, Guard cartridge with holder, 5 µm, 120 Å, 4 x 10 mm
Utilizing highest purity and enhanced mechanical stability silica and pure bonding reagents, BR-C18 bonded phases have been innovatively and specially designed to ensure maximum surface coverage and full end-capping, which leads to carbon content as high as 19.0%. The bonding chemistry is completely controlled that results in very reliable column-to-column reproducibility. The maximum surface coverage allows BR-C18 to have exceptional stability, resulting in high pH stability in the range of 1.5 to 10.5.
Microsolv Technology Corporation Guard Column Cartridges, RP C18 PE,10um, 100A. 4.0mm ID x 10mm Length. 5/PK.
These Guard Column Cartridges are packed with 10µm, Cogent RP C18 PE™ Stationary Phase. They are double end capped ( fully ), with traditional bonding of an 18 carbon silane to the highest purity silica available.Designed to protect your 3.0, 4.0 or 4.6mm ID, RP C18 PE, Analytical Columns from particulate and contaminants that will adsorb to it. They are packed in Stainless Steel Tubes and have Stainless Steel Frits that are pressed into PEEK Frit Caps. These Guard Column Cartridges must be used with a Guard Column Holder.
Sepax Technologies Inc Sepax HPLC Column Bio-C4, Guard cartridge with holder, 5 µm, 300 Å, 2 x 10 mm
Monomeric and fully endcapped Bio-C4 packing is bonded with butyl groups that lead to moderate hydrophobicity. Bio-C4 packings of 300 Å pore size selection are ideal for high resolution mapping of peptides and separation of intact proteins, and natural and synthetic peptides.
Sepax Technologies Inc Sepax HPLC Column Antibodix WCX, NP10, 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.
Optimize Technologies EXP Guard Column Cartridge, 1.5mm x 5mm, HILIC, 1.8µm, 3pk
The EXP™ Guard Column cartridge system is rated to 15,000psi with hand-tight replaceable cartridges. This unique design connects directly to any UHPLC column with the auto-adjusting Titanium Hybrid Ferrule and EXP™ Fittings, providing repeated zero-dead-volume connections and easy adjustability between various column types. Free-Turn™ architecture allows the user to change cartridges by hand without breaking fluid connections on the holder inlet/ outlet. The combination of low-dispersion and ultra high-pressure capabilities provides effective protection with negligible effects on retention time, plate count, and peak shape. Use with EXP™ Direct Connect and In-line Holders.
