Ionic chromatograph/Dionex ICS-1600/Dianex ion chromatograph Dionex ICS-1600

Ion chromatograph/Dionex ICS-1600

The Dionex ICS-1600 ion chromatograph is designed for isocratic elution and can also have gradient elution function when used in conjunction with the automatic elution solution generator (RFC-30). Optional chemical reagent free electrolysis sample pretreatment device (RFIC-ESP), utilizing valve switching and electrolysis water principle, can be used for different pretreatment of various matrix samples. When equipped with the online circulation device for shower solution (RFIC-ER), the ICS-1600 can work continuously for four weeks without the need to replace the shower solution. Combined with continuous automatic regeneration of microfilm suppressors and chameleon software (Chromeleon) ®) Using it can make it convenient for users to use.

The main features of the Dionex ICS-1600 ion chromatograph are:

LCD touch panel
The operator can set the main parameters of the instrument through the LCD touch sensitive display panel and monitor the working status of the instrument in real time.

double-piston pump
The dual piston reciprocating pump can make the instrument run more smoothly, providing a stable operating environment and detection effect.

column oven
A stable column temperature chamber ensures the stable operation of the instrument. The design concept of the rinsing solution preheating device is to stabilize the temperature of the rinsing solution entering the chromatographic column. The transparent column temperature box shell allows the operator to observe the working condition of the chromatographic column without opening the box.

Digital conductivity detector
The conductivity detector in digital output mode has intelligent functions and can automatically adjust the range within 0-15000 µ S to adapt to the analysis of complex matrix samples with large concentration differences, with a resolution of 0.00238 nS. The analog output mode is also compatible with this detector. The temperature control performance of the conductivity detector has been improved to make it stable, and the impact of changes in ambient temperature on the detector can be ignored.

Fully automatic electrolytic suppressor
The ICS-1600 ion chromatograph can manipulate SRS and Atlas suppressors. Continuous automatic regeneration type anion and cation suppressors can avoid the use of acid or alkali for regeneration. The electrolytic suppression function can improve the signal-to-noise ratio of the measured ions and enhance sensitivity while reducing background conductivity.

Leakage detection and waste liquid tank
The built-in optical leak sensor and waste liquid tank provide fast leak response and leak protection for the instrument. The parts of the whole machine that come into contact with the rinsing solution are made of biologically inert PEEK material, which protects the entire system from metal contamination and is compatible with acid and alkali to a certain extent.

Dionex ICS-1600 electronic log function of ion chromatograph
Real time monitoring of all working states of the instrument is possible, and optional chemical free rinsing solution online circulation device and RFIC-ER chemical free rinsing solution online circulation device can operate normally and stably for 28 consecutive days without changing the rinsing solution. During these 28 days, users do not need to replace the rinsing solution or redo the standard curve. The automatic sample pretreatment device (RFIC-ESP) is equipped with a chemical free electrolytic sample pretreatment device (RFIC-ESP), which can be used for different pretreatment of various matrix samples by utilizing valve switching and electrolysis water principle, simplifying the experimental process.

Optional shower solution automatic generation device (RFC-30)
When used in conjunction with the RFC-30 automatic rinsing solution generator, it can have a gradient rinsing function.

RFIC-ER "Sample only" eluent online circulation system
The online circulation device for rinsing solution (RFIC-ER) is a simplified solution launched by Dian Company for conventional ion detection. The system uses electrolytic suppressors to regenerate the rinsing solution, which enables continuous operation of the system and reduces the cost of rinsing solution and waste liquid discharge. Using the RFIC-ER system, users only need to prepare a 4L rinse solution to operate normally and stably for more than 28 days without changing the rinse solution, reducing the pain of frequent rinse solution configuration and providing customers with a simple, easy to operate, reproducible, and stable ion chromatography system.

RFIC-ER principle
The substances flowing out from the cathode and anode of the suppressor are eluent solution, water, hydrogen gas, oxygen gas, and anions and cations in the sample. The RFIC-ER system performs online degassing, deionization, and purification of other trace pollutants from the liquid flowing out of the suppressor outlet, which can be recycled as a regenerated rinse solution. The RFIC-ER system can be used in conjunction with carbonate/bicarbonate and methanesulfonic acid (MSA) eluents. The RFIC-ER system can generally be used continuously for about 4 weeks, and the operator only needs to perform injection operations. The Chromeleon workstation can monitor the usage status of the eluent, capture column, and purification column in real-time. The RFIC-ER system is highly suitable for detecting common cations and anions in simple matrices, while RFIC-EG is suitable for customers who need to face samples with relatively complex matrices or customers who require gradient elution.

Automatic rinsing solution generator
The Reagent Free Ion Chromatography (RFID) technology, which uses only water and is free of chemical reagents, was developed by Dian Company to solve the problems that scientists often encounter when conducting chromatographic analysis, such as cumbersome manual configuration of eluent and easy introduction of manual errors, oxidation of eluent placement, baseline drift in linear gradient elution process, and poor repeatability of experimental results. The basic principle of technology is to use electrolysis of water: electrolysis of water produces eluent online, electrolysis of water produces cations and anions required for conductivity suppression, and electrolysis of water completes online regeneration of the capture column, allowing ion chromatography analysts to complete all experiments with high-purity water. RFID technology further saves analysis time and labor, reduces instrument usage costs, eliminates errors caused by manual preparation of eluent, and stabilizes the reproducibility of analysis. The analysis results from different days, months, laboratories, and individuals can be consistent. Analysts no longer need to regularly prepare rinse and regeneration solutions, reducing the opportunity to come into contact with chemical reagents, which is a change in traditional laboratory analysis methods. The automatic generation device for rinsing solution (RFIC-30) can make the ICS-1600 ion chromatography a reagent free ion chromatography system, allowing the original constant current pump system to easily and automatically complete the rinsing of multiple steps and first-order linear gradients.
