In times of automated production, it is becoming increasingly important to be able to inspect the goods produced automatically for possible defects. Therefore, x-rays can be used to determine solid, powder or liquid samples to identify ingredients or defects. The field of applications includes research and development, metal and building material industry, pharmaceutical industry, geological exploration, sample examination and production monitoring.

Application requirements

  • Low vacuum
  • High reliability
  • Low power consumption

How does it work?
In principle, X-ray applications involve using an X-ray beam to analyze the samples to be examined for possible defects and ingredients. For this purpose, an X-ray tube is used to generate primary X-rays which are focused on the sample. Either the sample emits characteristic X-rays, which can be recorded with different detectors, or the sample is transilluminated. In this case, an X-ray film is used to produce an image of the transilluminated sample. Example applications are X-ray fluorescence analysis, X-ray photoelectron spectroscopy and X-ray diffraction.

Because of the low vacuum pressures required in the various X-ray applications, the turbo pump used is the heart of the vacuum system. In order to achieve the desired pressure range, you also need a backing pump. Various dry backing pumps are available, such as diaphragm pumps, multi-stage Roots pumps or our new scroll pumps. Pfeiffer Vacuum offers you a broad range of different measurement equipment to provide you with an overview of your working pressure. With the RS-485 interface, most Pfeiffer Vacuum products can communicate with one another, giving you just one controller for your entire vacuum system.
