HPLC Guard Columns and Cartridges
Sepax Technologies Inc Sepax HPLC Column HPLC Guard Column, SRT-10 SEC-2000, 10 µm, 7.8 x 50 mm
Utilizing proprietary surface technologies, SRT-10 and SRT-10C SEC phases are made of uniform, hydrophilic, and neutral nanometer thick films chemically bonded on high purity and mechanically stabilized 10 µm silica. The well-controlled surface chemistry results in excellent lot-to-lot reproducibility. Our unique bonding chemistry, coupled with the maximized bonding density, allows SRT-10 and SRT-10C SEC phases to provide high stability and negligible non-specific interactions. SRT-10 and SRT-10C packings have large pore volume, resulting in high separation resolution. Typical applications for SRT-10 and SRT-10C columns include separation and detection of biological molecules and water-soluble polymers in aqueous buffers.
Sepax Technologies Inc Sepax HPLC Column Antibodix WCX, NP10, Guard cartridge with holder, 2 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.
Sepax Technologies Inc Sepax HPLC Column Bio-C18, Guard cartridge with holder, 3 µm, 300 Å, 4 x 10 mm
Wide range of pore sizes and high compatibility with 100% aqueous phases make Bio-C18 columns ideal for high resolution mapping of peptides and separation of natural and synthetic peptides and small proteins. The specially designed surface bonding chemistry and the pore sizes allow for extended retention and selectivity for polar and hydrophilic compounds, such as peptides and amino acids. C18 monolayer formed by special bonding chemistry does not collapse in pure aqueous solution.
Waters Corp DeltaPak C4 Guard Column, 100Å, 5 µm, 3.9 mm X 20 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.
Waters Corp Spherisorb SCX Guard Cartridge, 80Å, 5 µm, 4.6 mm X 30 mm, 3/pk
Spherisorb SCX columns contain an anionic silica-based sorbent. This strong cation- exchange sorbent is used to separate positively charged ionic species.
Waters Corp Nova-Pak C8 Sentry Guard Cartridge, 60Å, 4 µm, 3.9 mm X 20 mm, 2/pk
Nova-Pak C8 columns are general purpose, silica-based, reversed-phase C8 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 ACQUITY UPLC HSS Cyano (CN) VanGuard Pre-column, 100Å, 1.8 µm, 2.1 mm X 5 mm, 3/pk
ACQUITY UPLC HSS CN chemistry is an ultra-performance general purpose propyl cyano bonded phase that provides superior peak shape for bases, increased retention, and extremely long column lifetimes at low pH. ACQUITY HSS CN columns are fully scalable and transferable to HPLC separations.
