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.

Suppressor (/Anion/Cation)	Equilibrium Curve of Suppressor

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.

• Full PEEK flow system for protection from metal pollution, high pressure, acids and alkalis and compatibility

with organic solvents.

• High-speed data transmission and processing capabilities and automatic identification,  control and real-time

monitoring of the operating state of instrument components to ensure continuous and stable analysis.

• Advanced digital thermal conductivity detector with high sensitivity, high stability to ensure

 accurate and reliable results.

• Optional eluent generator to achieve automated eluent preparation.

Pump Head (PEEK)	ACE Software

 

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.
DM-100/DM-101 On-line Degasser
Usages:
DM-100 /DM-101 on-line degasser can be used for Nanbei NBIC-2800 series ion chromatograph,
Nanbei LC-5500 series high-performance liquid chromatograph, or ion chromatograph and liquid
chromatograph from other manufacturers.
Features:
On-line degasser has the features of high degassing efficiency, easy installation, fast baseline
equilibrium, no drift, and low noise regardless of whether using isocratic elution or gradient elution.

Installation: NBDM-100 / NBDM-101 on-line degasser can be equipped with 1 to 4 degassing channels according to customer requirements. Either horizontal or vertical degasser orientation is selectable based on the overall structural design of the chromatography system being paired with. The on-line degasser can be installed between the reservoir tanks and infusion pumps.
