HPLC Guard Columns and Cartridges
Waters Corp Spherisorb C8 Guard Cartridge, 80Å, 5 µm, 4.6 mm X 10 mm, 3/pk
Spherisorb C8 columns are general purpose, silica-based reversed-phase columns that contain an Octyl ligand. These USP L7 columns are used when you require a less retentive sorbent compared to the Spheriorb ODS columns.
Sepax Technologies Inc Sepax HPLC Column Bio-C18, Guard cartridge with holder, 5 µm, 300 Å, 2 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.
Sepax Technologies Inc Sepax HPLC Column HPLC Guard Column, SRT SEC-2000, 5 µm, 7.8 x 50 mm, Light Scattering SEC
Utilizing proprietary surface technologies, SRT SEC phases are made of the uniform, hydrophilic, and neutral nanometer thick films chemically bonded on the high purity and enhanced mechanical stability silica. This proprietary surface technology results in excellent column-to-column reproducibility. The nature of the chemical bonding and the maximum bonding density of the thin film benefit SRT SEC phases with high stability and negligible non-specific interactions. Along with the widest pore size selection of 100, 150, 300, 500, 750, 1000 and 2000Å, SRT SEC packings have highest capacity that enables highest resolution.
Waters Corp µPorasil Silica Radial-Pak Guard, 125Å, 10 µm, 40 mm X 10 mm, 2/pk
Waters µPorasil 10µm silica packing material provides high-efficiency and low backpressure.
Waters Corp DeltaPak C18 Radial-Pak Guard, 300Å, 15 µm, 40 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.
Waters Corp DeltaPak C4 Radial-Pak Column, 300Å, 15 µm, 25 mm X 100 mm, 1/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.
