Product Details
Ion Chromatography adopts a full PEEK constructed dual-piston pump and flow system, self-regenerating electrochemical suppressor and automated eluent generator. Under the control of the powerful “Ace” software, the IC-2800 features ease of use, fast start up and reliable and stable performance. 
The electrochemical suppressor is specifically designed to be continuously self-regenerating. Since the eluent has high background conductivity, chemical inhibition must be done so that signals from analytes can be detected.
The inhibition of background conductivity is achieved through the reaction of CO32- and HCO3- in the eluent with H+ produced by electrolysis to generate H2CO3 of low conductivity during anion analysis and the reaction of H+ in the eluent with OH- produced by electrolysis to generate H2O.
H+ or OH- ions are produced by electrolysis without addition of extra eluent to realize automatic regeneration of ion exchange membrane.
Self-regenerative electrochemical suppressors for anions and cations are provided with the features of large inhibition capacity, low background conductivity (ppb level), low dead volume, rapid equilibrium, good repeatability, simple operation, easy maintenance etc.
Full PEEK double plungers and low pulsation infusion pump with wide range of flow rates, stable operation and low maintenance costs.
All instrument parameters are controlled through software and are displayed in the interface. The Ace chromatography software is powerful and easy to understand.
The instrument can also be operated through the front panel. The real-time status of each component can be monitored during the entire analysis process.
