Dionex DX120 Ion Chromatography System
- EQUIPMENT DESCRIPTION
The Dionex DX-120 Ion Chromatograph offers either remote control from a PeakNet workstation, or using the front panel keypad and display, for a local control. The PeakNet workstation uses a computer with PeakNet software and a Dionex DX-LANO interface card. Limited remote control is also available using TTL signals. Using conductivity detection, the Dionex DX-120 Ion Chromatograph enables isocratic ion analysis. The DX-120 Ion Chromatograph includes an injector valve, a detector and a single piston pump in an integrated system. Chromatography components include columns, Self-Regenerating Suppressors, and a conductivity cell, ordered separately. Components for this ion chromatography system are mounted on the inside of the DX-120 door. Samples can be loaded manually through a port on the front, or injected automatically using an AS40 autosampler.
The Dionex DX-120 Ion Chromatograph pump is a single piston pump that can deliver a flow rate from 0.5 to 4.5 ml/mn. The eluent flows from the pressurized containers through the pump from the bottom to the top of the pump. The eluent then goes to the bleeding valve, pulse damper (that gives the pump the necessary back pressure), and injection valve of the DX-120 Ion Chromatograph (or rheodyne valve of the AS3500 autosampler). The self-regenerating suppressor (SRS) in the Dionex DX-120 Ion Chromatograph consists of alternating layers of high capacity ion exchange screens and ion exchange membranes separating the electrodes. The screens of this ion chromatograph create a convoluted low volume flow path for the eluent and provide an ion transport path for the ion exchange process. The SRS requires a constant water feed through the regenerant chambers to achieve suppression.
The DX-120 Ion Chromatograph can be ordered as a either a single-column system or a dual-column system. The dual column system allows for switching between columns or between two eluents (eluent select mode). In the eluent select mode, the DX-120 can perform step gradients.
