It accommodates a container for solvent bottles, built-in high-efficiency on-line degasser and four-way gradient valve. Degasser unique design 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. Extremely low internal volume of each Teflon AF® channel (480 μl) offers very fast equilibration and very short startup times compared with PTFE degassing channels which have the same degassing efficiency.
Four-way gradient valve is controlled from the pump ECP2010 and 2010H and gradient box ECB2004B must be ordered with the pump. Pumps have new sophisticated electronics which allows achieving precise low-pressure gradient, i.e. gradual changes of mobile phase composition by mixing up to four liquids at the pump’s entry. It is also possible to predefine the percentage of composition when using the pump in isocratic mode. Gradient profile can be defined from computer or manually using display and keypad.
Up to 6 mobile phase reservoirs LCT 02 (1L)may be put into the box.
