1、 Equipment principle and advantages

EXAFSDesktop X-ray absorption spectrometerBased on the principle of Extended X-ray Absorption Fine Structure (EXAFS), the local structure within 0.3-1.0 nanometers around the absorbing atoms is measured to analyze parameters such as atomic spacing, coordination number, and element type. Its core advantages lie in:

Not dependent on synchrotron radiation source: Traditional XAFS technology relies on synchrotron radiation source, while desktop devices achieve transmission/fluorescence dual-mode measurement under non synchrotron radiation conditions through high-resolution monochromators (such as spherical curved crystals) and SDD detectors, making daily laboratory use possible.

Multi element detection capability: It can measure different types of atoms separately, distinguish neighboring atom types, support the detection of low concentration samples in parts per million, and is applicable to both ordered and disordered substances.

High precision and flexibility: With an energy resolution of 0.5-10 eV, it supports testing of solid, liquid, and gaseous samples and is equipped with transmission in-situ electrochemical cells, high and low temperature electromagnetic in-situ cells, etc., to meet diverse experimental needs.
