Relying on years of accumulated international standard library, each curve is established from dozens of standard samples, with more data points than the analysis curves established on site.
The unique calibration software can not only correct spectral interference, but also deduct background interference, improving the accuracy of analysis results, with an accuracy (relative standard deviation) better than 1%.
Saved users the cost of purchasing standard samples.

Spark data acquisition and processing system SPARK-DAT (optional)
Traditional direct reading spectrometers can only obtain elemental information in metal materials. Scanning electron microscopy is usually used to investigate the microstructure and chemical reactions between elements. The ARL 4460 metal analyzer equipped with single spark data acquisition and processing technology SPARK-DAT can not only perform elemental analysis, but also achieve inclusion analysis. This technology is mainly used for:
1. Phase analysis (such as acid soluble aluminum and acid insoluble aluminum in steel)
2. Analysis of inclusions in steel: such as CaO, Inclusions in CaS aluminum, such as TiB2, MgO
3. Cleanliness analysis
4. Improve the analytical performance of trace elements
