A tungsten probe is a probe or detector made of tungsten for detection, measurement or analysis. Tungsten has some advantages as a detection material in some scientific experiments, instruments and technical applications due to its high melting point, high hardness and good electrical conductivity. The main application areas of tungsten probes are:
1. Tungsten probes in electron microscopes: Tungsten tips are often used as probes in electron microscopes for high-resolution imaging and characterization of samples.
2. Scanning Tunneling Microscopy (STM): Tungsten tips may also be used in STM, a microscopy technique capable of achieving atomic-scale resolution.
3. Tungsten probes in chemical analysis: In some chemical analysis technologies, such as mass spectrometers, tungsten probes may be used for sample analysis.
4. Tungsten probes in materials research: In some materials science research, tungsten probes may be used to study the properties and structure of materials.
