YMC America, Inc ODS-AQ guard 200A 5um 10x10mm
YMC-Pack ODS-AQ is a unique reversed-phase material with both a hydrophobic high carbon loading and a relatively hydrophilic surface Because of the hydrophilic surface ODS-AQ can be wetted with polar eluents It provides chromatographers reproducible retention and excellent peak shape in highly aqueous mobile phases including 100% water This is due to the C18 ligands on ODS-AQ actually being lifted from the surface by the action of the eluents penetrating the silica pores Selectivity on YMC-Pack ODS-AQ can be subtly different from that seen on conventional ODS columns Differences in selectivity are most often encountered when analyzing mixtures of relatively polar compounds Typically longer retention and greater resolution are observed with ODS-AQ Available in both 120 and 200 pore sizes YMC-Pack ODS-AQ is well-suited for analysis and purification of peptides and other biomolecules

Optimize Technologies EXP2 Replacement Stems, 0.17µL, 2.7µm HALO, C18, 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
