Waters Corporation Prep Guard Cartridge, 5 μm, 19 mm × 10 mm
This silica-based, reversed-phase C18 guard cartridge protects analytical columns and maintains optimal performance. It offers balanced retention for polar and hydrophobic molecules, making it ideal for separations of various compound types.
- Constructed from the same packing material as the analytical column for compatibility.
- Inserted between the injector and analytical column to prevent impurities and suspended solids.
- Designed for direct attachment to the column, minimizing excess volumes and reducing leaks.
- Manufactured in a cGMP, ISO 9001 certified plant using ultra-pure chemicals.
- Each batch of packing material undergoes chromatographic evaluation with acidic, basic, and neutral analytes.
- Validated and verified to ensure optimal performance, enhancing selectivity, sensitivity, and speed of studies.
- Operational up to a maximum of 45 °C.

CT99S03-02Q1GC: Carotenoid, 3um, 20X2.1mm Cartridge, pk/5
Optimize Technologies EXP2 Stem Trap Kit, 0.17µL, 3.0µm EXP, 3.0µm EXP, C4
A standard EXP™2 Stem Trap Kit includes (1) EXP™2 Stem Holder and (3) packed stems. Specialized features, patented technology, precision engineering and state-of-the-art manufacturing make the new EXP2 Stem Trap an unbeatable choice for ultra high-pressure trapping applications. Its slim architecture allows it to easily fit into crowded instrument compartments or to connect directly to tightly-spaced injection ports. When tightened by hand, the EXP2 Stem Trap seals to 8,700+ psi. Additionally, the product can be wrench tightened to 20,000+ psi (1,400+ bar). The unique packed floating stem installs directly into any 10-32 port and automatically adjusts to provide a perfect ZDV connection. The replacement stems are low volume/ low-dispersion, intended for many repeat uses and is available with various bed volume and custom packing options. This product is recommended for nano flow applications.

The unique packed floating stem installs directly into any 10-32 port and automatically adjusts to provide a perfect ZDV connection. The new EXP2 design incorporates an integral ferrule into the front-end of the holder so there is no separate ferrule to lose! The replacement stems are also low volume/ low-dispersion, intended for many repeat uses and is available with various bed volume and custom packing options. This product is recommended for nano flow applications. For use with EXP™2 Stem Holder Only

Optimize Technologies EXP Trap Cartridge, 1.5mm x 5mm, 3.0µm EXP, 3.0µm EXP, Phenyl-Hexyl, 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.
Sepax Technologies Inc Sepax HPLC Column Bio-C18, 5 µm, 200 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.
