Dionex - DX-120
Manufactured by Dionex
DX-120 Ion Chromatograph
The Dionex DX-120 Ion Chromatograph performs isocratic ion analysis applications using conductivity detection. The DX-120 is an integrated system, which includes a pump, detector, and injection valve. The chromatography components, including the column(s), Self-Regenerating SuppressorÔ (SRSÔ), and conductivity cell are ordered separately. These components are mounted on the inside of the DX-120 door.
The DX-120 can be controlled locally, using the front panel keypad and display, or remotely, from a PeakNet workstation. The PeakNet workstation consists of a computer with a Dionex DX-LANÔ interface card and PeakNet software (Release 4.30 or higher) installed. Limited remote control is also available using TTL signals.
The DX-120 can be ordered as a single-column system or a dual-column system. The dual-column system allows switching between two sets of columns (column select mode) or between two eluents (eluent select mode). In the eluent select mode, the DX-120 can perform step gradients.
