The core function of the graphite curved crystal monochromator is to precisely filter out the desired Kα characteristic radiation from complex X-ray signals. This process is based on the Bragg diffraction principle, utilizing the precise arrangement and curved shape of the graphite crystal lattice to achieve selective transmission of X-rays.

In practical applications, this component effectively eliminates interference from continuous X-rays, Kβ radiation, and fluorescent radiation generated by the sample itself. This filtering effect is particularly significant when analyzing samples containing elements such as manganese, iron, cobalt, and nickel using copper-target X-ray tubes.

Dandong Tongda offers both graphite curved crystals and flat crystals. The use of graphite curved crystal monochromators can enhance the peak-to-background ratio, reduce background noise, improve the resolution of weak peaks, achieve a reflection efficiency of n ≥ 35%, and lower the diffraction angle of the diffractometer. The mosaic spread is ≤ 0.55°, and the crystal surface can be tilted by ±2°. These parameters ensure the stable performance of the instrument over long-term use.

In X-ray analysis, the quality of data directly impacts the reliability of research conclusions. The graphite curved crystal monochromator significantly improves the quality of the collected signals by enhancing the peak-to-background ratio and reducing background noise.

For diffractometer applications, this component also moderately lowers the diffraction angle, making weak peaks more distinct and improving the instrument's ability to resolve trace components. While this improvement may seem minor, it can play a critical role in key experiments.
