JASCO supplies a range of accessories and modules to support the application of the LC-2000 HPLC system including solvent selection and column selection components.
Ternary and Quaternary gradient units LG-2080-04/02 Proportioning valves for use with the PU-2080 analytical pump
The LG-2080-02 ternary module or LG-2080-04 quaternary gradient module can be used with the PU-2080 analytical HPLC pump to make a gradient HPLC pump. The PU-2080 HPLC Pump provides extremely stable solvent delivery well suited to low pressure gradient formation using the proportioning valve. The pump’s gentle suction action prevents cavitation in the pump head and is able to provide stable delivery of both volatile and viscous solvents. The LG-2080-proportioning module delivers precise and reproducible gradients through the flow rate range for use with 2mm and 4.6mm ID columns. The wetted parts are fabricated from 316SS, fluoro-polymer and PEEK, permitting a wide range of solvents to be used.

DG-2080-53/54 three or four solvent In-line vacuum degasser Vacuum degassing by membrane separation
The DG-2080-53/4 Degasser removes dissolved gas such as O2, N2, and CO2 from a solvent by passing the solvent through a special fluoropolymer membrane tube under vacuum. As degassing by membrane separation is done under mild conditions there is virtually no effect on the solvent composition.
