An X-ray tube is a device capable of producing X-rays. The XRF fluorescence spectrometer uses the strong penetrating ability of X-rays to illuminate the surface of the object to be tested and excite fluorescence to detect the types of elements contained in the object to be tested.
X-ray tube is an indispensable main component and the main consumable in XRF instrument. If you plan to purchase an XRF fluorescence spectrometer for your experiment, you must know something about X-ray tubes.
X-ray tubes commonly use target materials such as tungsten, molybdenum, chromium, silver, and rhodium. Different target materials produce X-rays with varying energy ranges, making them suitable for analyzing different types of elements. For example:
The power range of X-ray tubes typically falls between 10 watts and 4000 watts. Higher power produces stronger X-rays with greater penetration capabilities, making high-power X-ray tubes suitable for applications requiring deep penetration, such as:
The voltage range of X-ray tubes is usually between 30 kV and 100 kV. Higher voltage produces higher energy X-rays, suitable for analyzing materials of different depths and densities. Specific applications include:
The structure of X-ray tubes mainly includes side-window, end-window, and transmission target types. Different structures are suitable for different applications:
X-ray tubes can provide different focal spot sizes to meet various application needs:
By understanding the different types and characteristics of X-ray tubes, users can select the most suitable X-ray tube for their specific application needs to achieve optimal analysis results.
