High performance ion chromatography equipment
Introduction
NB-2800 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 NBIC-2800
features ease of use, fast start up and reliable and stable performance.

| AS-402 Autosampler | Repeatability of 20 Consecutive Analyses |
Features:
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.

Advanced Software System
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.
EG100 Eluent Generator - Ion Chromatography’s Helping Hand
Operators often need to change eluents of different concentrations and different types during
analysis, which creates heavy workload and is inevitable to cause human errors. To solve this
problem, Nanbei has launched a unique and automated EG100 eluent generator without an
additional degassing unit.
 |
| EG100 Eluent Generator |
EG100 - Features
1)Scientific and reasonable structure design and no additional degassing unit to ensure reliable generation
of eluent.
2)Only one pump is needed to achieve concentration gradient elution.
3)Both OH-, CO32- / HCO3- eluent for anion analysis and methanesulfonic acid eluent
for cation analysis are generated automatically.
4)Simple operation and control. Concentration of eluents can be set by software or though
the front panel.
5)High purity eluents are generated automatically without manual preparation to save operator’s time.
6)Eliminate errors due to manual eluent preparation and long term storage to greatly improve the
reproducibility of analysis results.
7)Further reduce the background conductivity and noise and therefore improve the detection sensitivity.
8)Reduce the time of the user’s exposure to chemical agents to create a safer working environment.
9)Can be independently controlled via the front panel and used with any ion chromatograph.Our high Quality Professional Ion Exchange Chromatography Instrument Ion Chromatograph
