www.agilent.comThe Pumps comprise one pump head unit with an optional solvent cabinet, a vacuum degasser (optional for the isocratic pump), and a multi-channel gradient valve (MCGV) for quaternary pumps, or an optional solvent selection valve (SSV) for isocratic pumps. The combination of the pump head assembly

This is especially important when running low pressure gradients since bubble formation can occur as a result of aqueous and organic solvent mixing during the gradient. e. Pressure XBridge™ columns can tolerate pressures of up to 6,000 psi (400 bar or 40
