Morphology and surface features
Our microscopy suite allows for detailed analysis of micro and nano-scale features at the sample surface as well as analysing the distribution of the material constituents within a sample.
Morphology, micro and nano-scale features / Topography
With our state of the art electron microscopy suit and extensive experience our microscopists can produce high resolution images of micro and nano-scale feature to allow you to better understand your materials characteristics. Atomic force microscopy also allows for 3D surface features to be measured for additional information.

Crystallographic
Using X-Ray techniques and ultra high resolution electron microscopy it is possible to determine and characterise structures of crystalline materials. From examining deposits in soil and clay samples, to discovering phases within metallics and their alloys, our range of equipment allows for detailed analysis of most materials.

Failure analysis
The ETC provides an expert service in Failure Analysis of engineering components and products. Using combination of microscopy and spectroscopy, along with other analytical techniques, we can determine the underlying causes of failure; whether this be due to a weakness in design, material properties or, more commonly, the effect of operational or environmental factors.
We have experience in the investigation of packaging materials and systems, marine structures, road and rail transport equipment, aerospace engineering, microelectronic devices and general engineering components
Microplastics identification and quantification
Microplastics are particles of plastic less than 5mm in size. They can be categorised in two groups; primary microplastics are originally created as small particulates to serve a specific purpose and secondary microplastics which are created through the abrasion of larger plastic over time. In either case, microplastics can be transported far from their source and microplastic pollution is found in almost all environmental settings and media including water, soils, flora and fauna.

The ETC in partnership with CGG Geoscience Laboratories provides a microplastic analysis service including rapid mass screening method for microplastic detection using automated mineralogy by QEMSCAN®, micro-FTIR and thermal analyses to deliver data on microplastic identification, composition, quantification and morphological classification. This workflow can deliver data from a large volume of samples significantly quicker (e.g. 5 days to analyse between 100 and 200 samples, dependent on scanning resolution) than existing manual and optical micropollutant identification techniques. This has huge time saving implications when data is needed to inform policy and guide decision-making.
This effective workflow is designed to help stakeholders, including industry, charities, NGOs, local authorities and government agencies identify high concentrations of microplastics and areas of plastic leakage and wastage where they may be entering the food chain or natural environment. In addition, this approach can be used to determine a ‘Microplastic Pollution Index’ to quickly identify pollution ‘hot spots’ with high concentrations of microplastics (e.g. close to fisheries, other food supply chains, local wastewater and drinking water supplies) and highlight areas which need attention for mitigation strategies or where pollution limits are being exceeded. This saves organizations time and money so that efforts can be focused on specific areas. A long-term monitoring service can be provided to show whether plastic concentrations are reducing in response to mitigation measures.
