Ion exchange chromatography is a separation technology. The dissociatable ions on ion exchange resin exchange reversibly with the solute ions with the same charge in mobile phase.
Ion Chromatography Flow Diagram
Ion exchange chromatography is a separation technology. The dissociatable ions on ion exchange resin exchange reversibly with the solute ions with the same charge in mobile phase. Ions are separated because of their difference in affinity to ions exchangers. So ion chromatograph is generally applicable to the separation and detection of hydrophilic anions and cations.
After the sample is injected, the ions to be analyzed are exchanged with dissociatable ions on the ion exchange resin at first (i.e. retained on the analytical column). When NaOH solution is used as eluent to analyze F- , Cl- and SO4 2- in the sample, the ions retained on the analytical column are replaced by OH- in the eluent, and the ions with weak affinity to the resin are eluted firstly. This is the separation process of ion chromatography. The eluent is suppressed by a chemical suppressor which can reduce the background conductance of the eluent. Then the ions to be analyzed can be measured accurately when it entered into the conductivity cell, and the detection signal can be outputted.
As a new generation of intelligent dual channel ion chromatograph, CIC-D300 plus is the latest ion chromatograph independently developed and produced by SHINE in terms of software and hardware. Each channel operates independently at the same time without mutual interference, realizing the simultaneous detection of cation and anion.
CIC-D300 plus highlights:
1.10 inch HD touch screen: real time display of flow path and operation status of the instrument;
2.Built-in double membrane eluent generator: no need degassing pipe and capture column, has pressure resistance of 30MPa, simpler flow path and smaller dead volume;
3.Ultra-pure ion purifier: it can purify water online and reduce the water requirements of the instrument, so as to reduce the baseline background and improve the signal-to-noise ratio;
4.Suction sampling system: use peristaltic pump to suck samples to reduce cross pollution at the injection port;
5.The gas-liquid separator will remove most of bubbles entering the flow path, and the constant pressure and low pressure degasser will continuously remove the residual gas dissolved in water;
6.Secondary infusion system: plunger pump and peristaltic pump secondary infusion system, combined with ultra pure on-line purification module and low-pressure gas-liquid separator, provide the most stable infusion scheme for the system.
7.Integral heating and insulation system: multi-point temperature control and overall insulation design are used to deal with extreme environment, and provide eluent preheating for flow path to ensure instrument stability;
8.Powerful safety assurance system: including eluent consumption alarm, liquid leakage alarm, low pressure alarm, overpressure alarm, fault alarm to reduce possible hurt by misoperation.
