Malvern Panalytical Unveils Epsilon Benchtop 4 Chemical Analysis Tool

Material characterisation technology specialist Malvern Panalytical is pleased to announce the launch of its latest high-performance benchtop analysis tool, Epsilon 4.

Built on the experience and success of the proven Epsilon 3 range of XRF spectrometers, the Epsilon 4 is a multi-functional instrument opening new applications for industries such as mining, pharma or oils and fuels who are obliged to comply with international regulations and test methods.

Combining the latest advances in excitation and detection technology with mature software and a smart design, the analytical performance of the new benchtop instrument approaches the one of more powerful and floor-standing spectrometers.

Due to its low infrastructural requirements, Epsilon 4 can be placed next to the production line anywhere in your process.

Its high performance enables most applications to be operated at ambient conditions, reducing costs for helium or vacuum maintenance.

The unique low-drift metal-ceramic X-ray tube, designed and manufactured by Malvern Panalytical, delivers compliant results for years without the need for costly re-calibration.

The instrument can automatically process sample batches without the need for operator attention.

Epsilon 4 is a highly flexible tool available in a 10W version for elemental analysis (F - Am) in areas from research and development (R&D) through to process control.

For even higher sample throughput or extended light-element capabilities and in more challenging environments a 15W version is available, which can even analyse carbon, nitrogen and oxygen.

Malvern Panalytical product director Simon Milner said: "Epsilon 4 delivers the highest count rate in the market, while little or no sample preparation is required to achieve very fast and reproducible results.

"It is the perfect analytical tool for any industry needing to comply with increasingly stringent test methods and norms.

"Trust our experienced staff to work with you on tailored solutions for your analytical challenges."

February 2018 Webinar: Measuring Particles Size Using Dynamic Light Scattering (DLS) Processes

Dynamic Light Scattering (DLS), also known as both Quasi-Elastic Light Scattering and Photon Correlation Spectroscopy, is an advanced method of measuring particle size in a liquid or solution at the sub-micron scale.

The sensitivity of some modern systems is such that it can also now be used to measure the size of macromolecules in solution.

In this presentation Dr Mike Kaszuba will summarise how the technique works, what its size and concentration limits are and discuss its advantages and disadvantages.

The webinar will take place on 1 February from 10:30 to 11:30 Easten US and Canada time.

Speaker Dr Mike Kaszuba is a technical support manager at Malvern Instruments. He has a PhD from the Polytechnic of Wales, where he studied the physical biochemistry of liposomes using nuclear magnetic resonance techniques.

He followed this with postdoctoral research into liposomal drug delivery at the University of Manchester. Michael joined Malvern in 1996 as a product technical specialist and two years later was appointed in his current role, responsible for the product technical specialist and application groups based in the UK.

Who should attend?

You should attend if you are working with or are interested in dynamic light scattering and would like an overview of the technique, including its benefits and limitations.

What will you learn?

You will learn about how Dynamic Light Scattering works, including the generation and interpretation of the correlation function and how this is used to give particle size information.

Why attend?

This is an opportunity to get a basic overview of dynamic light scattering and its applications from one of Malvern Panalytical's Zetasizer experts.

Please contact Malvern via the enquiries form for more information.

Century of data shows sea-level rise shifting tides in Delaware, Chesapeake bays

The warming climate is expected to affect coastal regions worldwide as glaciers and ice sheets melt, raising sea level globally. For the first time, an international team has found evidence of how sea-level rise already is affecting high and low tides in both the Chesapeake and Delaware bays, two large estuaries of the eastern United States.

US EPA helps improve water infrastructure projects in Illinois

The funding of $485,000 will be used by the village to build a new pump station to connect to the DuPage Water Commission in order to purchase Lake Michigan drinking water.

Presently, Bartlett purchases around 60% of its drinking water from the city of Elgin, but now has decided to purchase all of its drinking water from DuPage County.

EPA administrator Scott Pruitt said: “President Trump has made updating our nation’s infrastructure a top priority, and this grant demonstrates EPA’s commitment to carrying out improvements.

“These types of investments help grow the economy while solving real environmental problems in local communities.”

EPA made the grant available to the village through annual appropriations process, a process through which the agency is occasionally directed to provide funding to specific entities for particular study, purpose or activity.

In this case, the funding was designated in 2009 for projects to improve drinking water infrastructure.

Bartlett Village president Kevin Wallace said: “The DuPage Water Commission has provided its members with a reliable water supply for many years.

“This is a huge and much anticipated infrastructure improvement for the Village of Bartlett, and we look forward to being commission members and soon being able to deliver high quality, softened Lake Michigan water to all of our residents.”

Recently, EPA had awarded $2.1m for the protection and restoration of wetlands and streams in California.

According to the agency, supporting aquatic resources can improve water quality, fish and wildlife habitat, flood protection and can offer recreational opportunities.

The agency had decided to provide funding in Napa River in Napa County, Southern California Coastal Water Research Project, Sacramento-San Joaquin Delta Conservancy, California State Coastal Conservancy and in Sonoma County.

Recent advances in understanding coral resilience are essential to safeguard coral reefs

The most urgent course of action to safeguard coral reefs is to reduce global greenhouse gas emissions, but concurrently there is also a need to consider novel management techniques and previously over-looked reef areas for protective actions under predicted climate change impacts. The conclusions were reached following a comprehensive review of the literature on the mechanisms of potential coral resistance and recovery across scales from global reef areas to the microbial level within individual corals.

Release of ancient methane due to changing climate kept in check by ocean waters

Ocean sediments are a massive storehouse for the potent greenhouse gas methane. But methane only acts as a greenhouse gas if and when it reaches the atmosphere. Environmental scientists recently set out to discover whether or not this ancient-sourced methane, which is released due to warming ocean waters, survives the journey from the seafloor and reaches the atmosphere.
