EA Technology has both the equipment and expertise to offer a wide range of microscopy and x-ray imaging services, with the experience to deliver maximum value from results through skilled, expert interpretation.
The optical microscope is a flexible and widely used tool for materials analysis and failure investigation, which provides more detail than examination by naked eye, often without any significant sample preparation time. Optical microscopy by our highly-trained personnel can be used to compare a range of materials or components, as well as identify the causes of fractures and material failures.
Optical microscopy provides a useful and flexible materials analysis tool, from low magnification observations of up to x40, to high magnification examinations of up to x1250, often with minimal preparation required.
Further preparation, such as cross sectioning, polishing and chemical etching, can reveal even greater detail of a component’s microstructure. Use of polarized light, phase contrast and Nomarski microscopy techniques is particularly useful when assessing the quality of XLPE cable insulation or other polymer materials.
A scanning electron microscope (SEM), equipped with an x-ray analyser, can produce superior images to those available from an optical microscope, offering far greater magnification and depth of field. Electron microscopy produces an accurate analysis of material surfaces and chemical composition, which is particularly useful in forensic investigations.
The surface of a fracture, seen under an electron microscope, can often reveal a great deal of information about the nature and cause of a fracture. SEM analysis allows examination of the microstructure of a material and its composition. These are useful in accessing the grade of material that has been used in a component or defects in manufacturing. Electron Microscopy can also be used for assessing the quality of and identifying degradation in a wide range of material samples used in the manufacture of electrical network assets and other components.
The addition of an x-ray analyser further enhances this service, allowing us to include analysis of the elements present quickly and easily. This is of particular value in identifying the nature and source of contamination or corrosion.
X-ray photography (radiography) is used to gain information about inner components of an assembly or piece of equipment before the assembly is dismantled or cut apart. It is particularly useful on assemblies that will split into many pieces when taken apart, making reconstruction of the original structure difficult, such as vacuum circuit breaker bottles or fuses.
