    Scanning electron microscope is a large analytical instrument, which is widely used in material science, life science, physics, chemistry and other fields. The scanning electron microscope is equipped with some special accessories, such as energy spectrometer, electron diffractometer, etc., so that the scanning electron microscope becomes a multi-functional, fast, intuitive and comprehensive surface analysis instrument. As a professional reliability third-party testing organization, T,C&A Lab's Scanning Electron Microscope Laboratory can analyze metals, ceramics, composite material and other materials according to ISO, ASTM and other standards. Welcome to contact our experts for consultation.

    Main advantages of scanning electron microscope

    • High resolution

    The resolution of advanced scanning electron microscope has reached about 1 nm.

    • Larger magnification

    The resolution of the electron microscope is much higher than that of the optical microscope. The highest magnification of the optical microscope is only about 1500 times, while the scanning microscope can magnify more than 10000 times.

    • Three-dimensional imaging

    The fine structure of the uneven surface of all kinds of samples can be observed directly.

    • Simple sample preparation

    Large-scale samples can be observed, from millimeters to centimeters; bulk samples do not need to be cut into ultra-thin slices.

    • Configure X-ray energy spectrometer

    Simultaneously observe the microstructure and analyze the composition of the microstructure.

    SEM has a wide range of applications in materials and metallurgy, including

    • Fracture failure analysis

    • Cause analysis of product defects

    • Coating structure and thickness analysis

    • Coating layer and thickness analysis

    • Material surface wear and corrosion analysis

    • Refractory structure and corrosion analysis
