New Ion Chromatograph Features Built-in Electrodialytic Suppressor
Jun 05 2020
Shimadzu, one of the world leaders in analytical instrumentation, has introduced the new HIC-ESP (Ion Chromatograph) featuring a built-in electrodialytic suppressor. This outstanding anion suppressor minimises band spreading and achieves high sensitivity and reliable performance for the quantitative determination of anions. The suppressor is rugged, providing stable functionality over long periods of operation. Furthermore, the system’s small footprint requires less bench space in usually densely-packed laboratories: the best things come in small packages. The HIC-ESP covers a wide range of applications in environmental testing, pharma, chemistry and food science.
The HIC-ESP modular inert flow path system integrates a system controller, degasser, pump, CDD detector with temperature controlled flow cell, autosampler, slim-line oven and the anion suppressor. This new ion chromatography system combines a number of valuable features providing highly-reliable analytical results: Excellent solvent delivery performance, low carryover, fast injection speed (as low as 10 sec), high sample injection precision and repeatability, precise oven temperature regulation and more.
High efficiency and stability
The new ICDS-40A anion suppressor is located between the IC column and the detector. The unit features a low-volume design combined with a unique multi-layered structure. With a folded membrane, it provides highly efficient electrodialytic background suppression and increased stability. The patent-pending design reduces peak spreading, increasing sensitivity for components with low retention such as fluoride, and improves separation from the water dip.
The ICDS-40A allows for analysis as well as self-regeneration simultaneously, shortening analysis cycle time and maximising workflow efficiency. Because the anion suppressor uses effluent from the detector as regenerant, it eliminates the need for cumbersome offline regeneration with environmentally unfriendly solutions such as sulphuric acid.
Seamless integration with software platform
In addition, the user-friendly ion chromatography system integrates seamlessly with Shimadzu’s LabSolutions platform. This allows users to easily manage parameter setting for IC analysis, batch analyses, auto-shutdown, data processing and report creation. Data integrity is assured with the addition of LabSolutions DB and LabSolutions CS.
Special features and benefits of the new HIC-ESP ion chromatograph include:
- Highly effective ion-exchange performance: The ICDS-40A is a highly efficient, electrodialytic membrane suppressor for ion chromatography. It offers stable reduction of electrical conductivity of the eluent at the time of detection, enabling high sensitivity analysis of inorganic anions.
- Minimised peak dispersion: The ICDS-40A anion suppressor has a smaller inner volume compared to conventional systems, resulting in less peak dispersion. It offers improved peak shape and good separation of early eluting compounds from the water dip and enables accurate measurement of e.g. fluoride that elutes early in a chromatogram.
- Small footprint: The HIC-ESP ion chromatography system combines with the Nexera slim oven CTO-40S for a compact design. With a width of only 420 mm, it needs just half the bench space required by other comparable systems.
