HPLC Guard Columns and Cartridges
Sepax Technologies Inc Sepax HPLC Column Polar-Imidazole, 10 µm, 120 Å, 4 x 10 mm
Utilizing highest purity and enhanced mechanical stability silica and pure bonding reagents, Polar-Imidazole phase is bonded with imidazole functional groups. With a polar and N-containing ring structure, Polar-Pyridine phase is a weak base and adequate for many applications, such as pharmaceuticals, peptides, sugars, and nucleotides.
Waters Corp Waters XBridge Premier BEH C8 Column, 2.5 μm, 4.6 × 150 mm
The XBridge Premier BEH C8 Column is engineered for UHPLC/UPLC, offering less retention than C18 columns for rapid method development. It integrates trifunctionally bonded BEH particles for a wide pH range (1-12) and MaxPeak High Performance Surface technology to minimize analyte/surface interactions, enhancing peak shape and signal.
- Less retentive than C18 columns, ideal for rapid method development.
- Wide usable pH range (1 to 12) with superior low pH stability and ultra-low column bleed.
- MaxPeak High Performance Surface technology reduces analyte/surface interactions, increasing recovery, sensitivity, and reproducibility.
- Reduces conditioning times and improves peak shapes.
- Good universal choice, stable across wide pH and high temperatures, simplifying mobile phases.
Optimize Technologies EXP2 Replacement Stems, 0.17µL, 2.7µm HALO, RP-Amide, 3pk
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 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
