This Dionex DAD HPLC System is in excellent condition.
The system includes:
- AS50 autosampler with thermal controller
- GP50 gradient pump
- PDA-100 diode array detector.
- Eluent bottles and syringe pump are also included.
- Cables and connectors
The advantage of Dionex is the all around PEEK construction. Software is not included.
Dionex AS50 Autosampler
The Dionex Autoselect AS50 Autosampler precisely delivers from 1.0 to 99.9 µL (in 0.1 µL increments) or 100 to 1000 µL (in 1 µL increments) of sample to an injection valve. During sampling, the tray remains stationary and a sampling needle arm moves from vial to vial. Up to 99 injections can be taken from each vial. The AS50 can be controlled locally, from the front panel keypad and display, or remotely, with a personal computer running Chromeleon software. The AS50 can be configured with PEEK flow paths and components for ion chromatography (IC) applications, or with stainless steel flow paths and components for high-performance liquid chromatography applications (HPLC).

Dionex GP50 Gradient Pump
The GP50 Gradient Pump is an integral part of a Dionex chromatography system. It is a microprocessor-based, dual-piston, variable-speed, gradient delivery system designed to blend and pump mixtures of up to four different eluents at precisely controlled flow rates. The pump can deliver the selected eluent composition isocratically, or as a multistep linear or curved gradient. A Digital Signal Processor (DSP) provides high speed control of pump flow and pressure.
Dionex EG40 Eluent Generator
The use of eluent generators in IC has several significant advantages. Separations can be performed using only deionized water as the carrier. Eluent generators produce high purity, containment free acid and base eluents on-line. The use of these high purity eluents can significantly improve the performance of ion chromatography methods.
