Specifications

The gradient box is suited for handling liquids in ECOM gradient systems.  It accommodates a container for solvent bottles, built-in high-efficiency on-line degasser and four-way gradient valve.
The degasser is a unique design that assures reliable operation and the highest level of continuous performance available without the need for helium degassing.  Up to four solvent lines may be degassed simultaneously by one unit.  One additional channel is reserved for degassing of gradient valve output.  The extremely low internal volume of each Teflon AF® channel (480 µL) offers fast equilibration and short startup times compared with PTFE degassing channels which have the same degassing efficiency.

The four-way gradient valve is controlled from the pump ECP2010.  Using sophisticated electronics, gradual changes of the mobile phase composition by mixing up to four liquids, precise low-pressure gradients can be achieved.   Isocratic modes can be predefined whereas gradient profiles must be programmed through the computer.5 independent degasser channels
