New ion chromatograph with patent-pending design covers a wide range of applications and has only half the usual size of bench space needed
Shimadzu 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: 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.
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 maximizing 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 sulfuric acid.
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.

52547pr@reply-direct.com New method for acidic herbicide analysis of waters and soils announced
Socotec has developed a new method for the acidic herbicide analysis of waters and soils. The organisation’s Environmental Chemistry division have been awarded UKAS ISO 17025 accreditation for their new LC-MS/MS instrument, which analyses a suite of acidic herbicides in groundwater, surface water, landfill leachates and trade effluents.
Offering a faster, more stable method of analysis, the instrument extracts 50 times less sample volume (10ml compared to 500ml) but still achieves the same sub parts per billion reporting limits (µg/L). This provides a quicker and easier way to test, store and transport samples, as well as generating a more robust set of results.
The LC-MS/MS instrument offers a host of additional benefits, including a higher sensitivity and faster instrument runtime, the latter of which ensures that a greater number of samples are analysed in a day. Sample preparation time and the need for regular instrument maintenance has also been reduced, as no derivatisation is required.
“Acidic herbicides require a highly selective and sensitive method of analysis due to their high water solubility, low volatility and heavy agricultural use,” said Becky Batham, Operations Manager, Laboratory and Analytical, Socotec UK. “With this in mind, the new LC-MS/MS instrument has been developed to more accurately and efficiently measure acidic herbicide presence in waters and soils, as well as to help maintain public and environmental safety.
“Gaining UKAS accreditation for this new testing method is a fantastic achievement for the Environmental Chemistry division, demonstrating their high level of commitment to developing new and innovative solutions for clients.”

Fighting microplastics ~ PerkinElmer and UK-based eXXpedition research team collaborate on ocean pollution Each year up to 8 mmt of
plastic ends up in our oceans. A concern for our seas, organisms who ingest microplastics and for us as seafood enters our global food chain.
email: For More Info, email: email:
To help understand the issue and how to develop effective solutions, eXXpedition, an all- women research team, set sail last October with PerkinElmer’s environmental testing and analysis solutions aboard. From the Azores and Antigua … to the Galapagos and Tahiti, the eXXpedition crew collected and analysed microplastic samples.

“On-board we have the PerkinElmer Spectrum Two FTIR spectrometer and the Spectrum 10 software which allows us to determine and classify microplastic samples gathered” said Dr. Winnie Courtene-Jones, eXXpedition Science Lead, University of Plymouth. “A key finding was the prevalence of polyethylene in surface water samples – a plastic widely used in food packaging, bottles, films and plastic bags.”
With COVID-19 making continued travel impossible, the eXXpedition team is back on dry land for now but continues to leverage PerkinElmer’s technologies to conduct ongoing research at the University of Plymouth; and has launched a Year of Virtual Impact online to keep the learnings, data sharing and conversation going strong.
