IC-2800 ion chromatograph Introduction
In view of the high background conductivity value of the eluent, without chemical suppression, the value of the conductivity signal from the analyte cannot be detected. The inhibition reaction is as follows: When performing anion analysis, CO32- and HCO3- in the eluent It reacts with H + produced by electrolysis to generate H2CO3 with low conductivity; during cation analysis, H + in the eluent reacts with OH- produced by electrolysis to generate H2O, thereby suppressing the background conductivity. The H + or OH- produced by electrolysis can realize the automatic regeneration of ion exchange membrane.
It can provide both anion and cation self-circulating regenerative electrochemical suppressors at the same time. The suppressor produced by it has large suppression capacity, low background conductivity (it can detect components as low as several ppb concentrations), small dead volume, fast balance, Good repeatability, simple operation and no maintenance. Features
1.The high-pressure pump and flow path design of PEEK material avoids metal pollution and can withstand high pressure, acid and alkali resistance, and reverse phase organic solvents
2.With automatic eluent generator, gradient eluent can be achieved under single pump conditions
3.Electrolytic self-regenerating micro-membrane suppressor (anion / cation), high suppression capacity, short equilibrium time, small dead volume, no need to manually prepare acid or alkali regeneration liquid, providing better chromatographic performance and less daily maintenance
4.On-line filtration of eluent, CO2 absorption and degassing device, easy to use, to ensure the reproducibility of analysis, to prevent contamination and decomposition of eluent
