HPLC Guard Columns and Cartridges
Sepax Technologies Inc Sepax HPLC Column Bio-C18, Guard cartridge with holder, 5 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 Styragel Guard Column, 20 µm, 4.6 mm X 30 mm, 100 - 10K, DMF, 1/pk
These Styragel Guard columns protect and increase the column lifetime of your Styragel 7.8 mm or 4.6 mm ID columns.
Tosoh Bioscience LLC TSKGEL OCTADECYL-2PW GUARD COL
Column, Guard; For 4.6mm I.D. Tosoh TSKgel Octadecyl-2PW column; Media: Polymer; 4.6mm I.D. x 1cm Length
Sepax Technologies Inc Sepax HPLC Column Bio-C4, Guard cartridge with holder, 5 µm, 300 Å, 4 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.
Waters Corp Spherisorb ODSB Guard Cartridge, 80Å, 5 µm, 4.6 mm X 30 mm, 3/pk
Spherisorb ODSB columns are general purpose, silica-based, reversed-phase C18 columns. The ODSB packing features intermediate ligand density with a specified carbon load of 11.5%.
Optimize Technologies OPTI-GUARD™ Biocompatible 1mm Guard Column, Anion Exchange (SAX), 5pk
OPTI-GUARD™ sets the standard for extremely low impact, easy to use pre-column protection. Designed for use with analytical (4.6, 3.0 mm i.d.) and narrow-bore (2.1, 1.0 mm i.d.) columns, the patented floating stem design automatically adjusts to any manufacturer's tube stop depth for a zero-dead-volume connection every time. The best part? It's no larger than a standard fitting. Connecting the OPTI-GUARD™ requires no extra tubing, maintaining the minimal impact philosophy that has made the OPTI-GUARD™ line so popular. As always, custom packing is available. Key Features include: 5 disposable hand-tight holders and cartridges, a ZDV Connection, automatic adjusting to any manufacturer's column, no extra tubing is required for connection, the product does not effect chromatography, and it is no larger than a standard fitting.
Sepax Technologies Inc Sepax HPLC Column Proteomix SAX, NP10, 10 x 50 mm
Sepax HPLC Column Proteomix SAX, NP10, 10 x 50 mm
Sepax Technologies Inc Sepax HPLC Column HPLC Guard Column, SRT-C SEC-500, 5 µm, 4.6 x 50 mm, Light Scattering SEC
SRT-C SEC phase, developed based on innovative surface coating technology, comprises of uniform, hydrophilic, and neutral nanometer thick film chemically bonded to high purity and mechanically stabilized silica. SRT-C, uses lay-down monolayer on porous silica as oppose to SRT of stand-up monolayer, offers ideal phase chemistry for hydrophobic samples like insulin, membrane protein monoclonal antibodies derivatized with polymer branches (polypeptide or PEG) separation.
Waters Corp Nova-Pak Cyano (CN) Sentry Guard Cartridge, 60Å, 4 µm, 3.9 mm X 20 mm, 2/pk
Nova-Pak HP CN columns are silica-based, cyano phases that are based on 4 µm particle technology. These columns can be used to achieve unique compound selectivity for both normal-phase and reversed-phase applications.
