GB/T 17359-2023 "Quantitative analysis by microbeam analysis and energy dispersive spectrometry" is a revision of the original standard GB/T 17359-2012, mainly targeting the application of energy dispersive spectrometry (EDS) in the quantitative analysis of elements with an atomic number not less than 11. This revision introduces new technical requirements and normative references to adapt to my country's technical conditions and increase operability.
| Dimensions | GB/T 17359-2012 | GB/T 17359-2023 | Comparison Notes |
|---|---|---|---|
| Terms and Definitions | Contains terms such as absorption correction and atomic number correction. | Delete terms such as absorption correction, and optimize the definitions of energy resolution and spatial resolution. | Delete obsolete terms and clarify technical details. |
| Sample Preparation | Requires the sample surface to be smooth and uniform. | Refine the requirements for sample conductivity and contaminant removal. | Increase conductivity requirements and strengthen cleaning specifications. |
| Instrument preparation | Specify the acceleration voltage range and detector stability. | Introduce new detector efficiency measurement methods and energy scale calibration requirements. | Increase detector performance monitoring and improve analysis accuracy. |
Peak identification:Automatic identification of spectral peaks by software, the influence of heavy peaks and escape peaks must be considered. For example, when analyzing light elements, Ti-K and VL lines may interfere.
Matrix effect correction:Includes ZAF (atomic number, absorption, fluorescence) correction methods. Samples with stoichiometric bonding (such as oxygen in silicate minerals) can calculate the light element content by difference method.
