Transmission Electron Microscopy
Transmission Electron Microscopy (TEM) analysis reveals crucial information on the internal structure of materials
Transmission electronic microscopy (TEM) expertise is widely sought, with a wide array of capabilities utilized in many different scientific, educational and industrial fields. Some examples include the characterisation of catalyst particle architecture, the assessment of size and shape for nano-metallic particles used in the electronics industry, the morphology of adhesive systems, and the exfoliation and distribution of nano-clay particles within epoxy systems for use within the aerospace industry.
TEM also provides important role within tissue analysis as part of metals and inorganic bioanalysis case studies, such as labelling with gold colloids and other staining techniques of tissue samples, to Good Laboratory Practice (GLP) standards.
Our experts combine state of the art transmission electron microscopy with decades of industry experience and essential insight. Transmission electron microscopes use magnetic lenses to focus magnified images onto phosphorescent screens or digital cameras, and utilises sample preparation no thicker than 60-80 nanometres, through which the electron beam is transmitted. It may include skilled ultramicrotomy and embrittlement by cooling, chemical fixation, and staining to impart contrast to the image. Ultra-fine particulates or dried latex materials may also be held on thin support films for examination.
TEM Analysis provided by our experts includes
- Degree of encapsulation of titanium dioxide within polymeric material
- Study of Biological Tissues to Good Laboratory Practice (GLP) standards
