In Which Laboratory Equipment Are Barium Tungsten Cathodes Used?

Barium tungsten cathodes are widely used in many laboratory equipment covering several fields of scientific research. Here are some examples of laboratory equipment where barium tungsten cathodes may be used:

Electron Microscope (SEM): An electron microscope is a microscope that uses a beam of electrons instead of light beams to observe a sample. A barium tungsten cathode can be used as an electron emission source to generate an electron beam for scanning and imaging the microstructure of the sample surface.

Transmission Electron Microscope (TEM): A transmission electron microscope is a microscope that passes a beam of electrons through a sample to observe its internal structure. A barium tungsten cathode can be used as an electron source to generate a high-energy electron beam for transmission electron microscopy imaging.

Electron Spectroscopy: Electron spectroscopy is used to analyze the surface composition and structure of materials. A barium tungsten cathode provides an electron beam for electron excitation and analysis of the sample.

Ion Trap Mass Spectrometer: Ion trap mass spectrometers are used to analyze and detect ions in a sample. A barium tungsten cathode can be used to generate an electron beam for ionization and excitation of ions in a sample.

Surface Plasmon Resonance (SPR) Devices: SPR devices are used to study biomolecular interactions such as protein binding. A barium tungsten cathode can be used to electronically excite the sample to generate plasmon resonance.

Photoelectron Spectroscopy: Photoelectron spectroscopy is used to study the electronic energy level distribution of materials. A barium tungsten cathode provides an electron source for exciting photoelectrons in the sample.
