Several questions about spectral analysis
Thread Content
Spectral analysis is divided into the following categories: 1. Total quantification: Analyzing the various components of that material. 2. Semi-quantitative: Only the alloying elements are analyzed, as opposed to full quantification. 3. Qualitative analysis: Only the alloying elements are analyzed, but the detected values for these elements fall within a certain range; it is primarily determined whether the alloy content lies within this range. Dear experts, is the above correct?
It can be roughly considered that way, but overall, the accuracy of spectral analysis (for handheld devices) is not very high. Moreover, the common handheld metal composition analyzers available today are designed to detect technical elements only, and they are unable to analyze non-metallic elements.
There are two types of analysis: qualitative and quantitative. Depending on the testing equipment used, quantitative analysis is further divided into absolute quantitative and semi-quantitative analysis, based on the accuracy of the analysis.
