Waters Corp Waters Guard Column, C18, 4 μm, 3.9 mm x 20 mm
The Nova-Pak C18 Guard Columns are silica-based, reversed-phase C18 columns designed for high-performance liquid chromatography. They utilize 4 μm particle technology to provide higher resolution and more efficient separations, while also extending the lifetime of analytical columns by protecting them from contaminants.
- General purpose, silica-based, reversed-phase C18 columns based on 4 μm particle technology.
- Offers higher resolution, more efficient separations, and faster chromatography compared to 5 μm columns.
- Can use shorter columns to reduce solvent consumption without compromising resolution.
- Designed to extend the lifetime of analytical columns by protecting them from contaminants.
- Comes with two guard columns per package.
- Guard columns and guard column holders are covered by a warranty program.
Sepax Technologies Inc Sepax HPLC Column Bio-C18, Guard cartridge with holder, 3 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.
Optimize Technologies EXP Trap Cartridge, 2.1mm x 5mm, 3.0µm EXP, 3.0µm EXP, SCX, 3pk
The Hand-Tight EXP™ Trap Column is rated to 20,000+ psi. This unique design connects directly to any injection valve (with 10-32 threads) or in-line with 1/16” tubing for unparalleled convenience and efficiency. The EXP™ System enables chemists to quickly remove detergents or salts which can affect the ionization process in MS work. This trapping technique can concentrate the sample directly on-line, allowing for increased recovery of precious sample material compared to off-line techniques. Free-Turn™ architecture allows users to change cartridges by hand without breaking fluid connections on the holder inlet/outlet. The EXP™ Trap Column family now offers packed beds available in 2, 5, 10, 15, 20 and 30mm lengths with diameters ranging from 1-4.6mm and bed volumes from 1.6-600µL. Please contact your representative directly if you're interested in a length other than 5mm.
Waters Corp XTerra Shield RP8 Prep Guard Cartridge, 125Å, 5 µm, 10 mm X 10 mm, 1/pk
XTerra Preparative RP8 columns are hybrid-based, reversed-phase C8 columns that incorporate Waters patented embedded polar group technology to improve peak shape performance for highly basic compounds. These first generation columns provide superior pH stability compared to a silica-based column. This product needs to be used in conjunction with other parts.
