Instrument features:
1. The invention of this device is beneficial for application method engineers to tap into the potential of the device. To facilitate the expansion of application scenarios;
2. Can analyze multiple elements at once;
3. This method is mainly a "dry" analysis technique, which directly excites solid samples (metal chips or powders);
4. The blank introduced by chemical reagents and vessels, as well as the basic elimination of environmental pollution; Do not use flammable, explosive, or harmful gases to the human body, nor use chemical reagents, which is beneficial for human health, safety, and environmental protection;
5. Easy to operate, the analysis process only requires weighing, excitation, and computer analysis to directly obtain the concentration of unknown samples;
6. When exciting the sample, each element has a different life cycle, so the function of element evaporation curve is needed to determine the analysis time period for different element integrals.
