ما الفرق بين مطياف XRF و EDXRF?

الأشعة السينية مضان (XRF) is a widely used analytical technique for identifying and quantifying the elemental composition of materials. Within the XRF family, there are two primary types of technologies: XRF المشتت للطاقة (edxrf) و Wavelength Dispersive XRF (WDXRF). Although they share the same fundamental principle—using X-rays to excite atoms and detect their emitted radiation—the two methods differ significantly in detection mechanisms, دقة, سرعة, and application scenarios.

في هذه المقالة, we’ll explore the key differences between EDXRF and WDXRF, and how أداة Vray’s EDXRF solutions can support your precise testing needs.

What Is EDXRF?

طاقة تشتت الأشعة السينية مضان (edxrf) uses a solid-state detector (such as SDD or Si-PIN) to measure the energy of emitted X-rays from a sample. It records the full energy spectrum simultaneously, making it a fast and flexible solution for multi-element analysis.

Key Features of EDXRF:

  • Faster analysis time – all elements are measured at once.

  • Compact and portable options available.

  • Lower cost and easier operation.

  • Ideal for on-site or general laboratory testing.

What Is WDXRF?

Wavelength Dispersive X-ray Fluorescence (WDXRF) uses diffraction crystals to separate X-rays by wavelength and measure them sequentially using a goniometer. This approach yields higher resolution and sensitivity, particularly for detecting elements with overlapping spectral lines.

Key Features of WDXRF:

  • Superior spectral resolution – better separation of closely spaced lines.

  • Higher accuracy and precision, especially for trace elements.

  • Stable for long-term laboratory use.

  • Typically used in large-scale industrial or research laboratories.
