[AI-EPR Q&A] Answers to Address User Concerns

In October 2024, CIQTEK officially launched the AI Electron Paramagnetic Resonance (EPR) Spectrometer. This series of products possesses AI-driven spectrum analysis and intelligent literature correlation and achieves a groundbreaking signal-to-noise ratio of 10,000:1, which is the highest in the field of EPR spectroscopy. For your reference, we have compiled the following questions and answers to address user concerns.

01. Is the AI spectrum analysis function only for simple free radicals? Can it analyze multi-electron systems?

The AI EPR Spectrometer's spectrum analysis function is not limited to simple free radicals and can also analyze complex multi-electron systems. Specifically, it can fit over 90% of free radical samples and support the analysis of multi-electron systems, including metal complexes and multi-component samples. Therefore, whether it's a single type or a more complex multi-electron structure, AI spectrum analysis is capable.

02. What is the source of data for AI spectrum analysis?

The data for the AI-EPR Spectrometer's spectrum analysis comes from multiple authoritative sources. The internal database contains over 24,000 substance components, 250,000 related published literature, and more than 200,000 measured data points from various universities, research institutions, and testing centers. These extensive data sources ensure the accuracy of AI spectrum analysis.

03. How does AI spectrum analysis perform on multi-spin systems?

AI spectrum analysis can effectively handle complex multi-spin systems and accurately distinguish and fit multiple components. However, multi-spin systems involve more complex parameters, which present greater challenges for analysis. Nonetheless, AI spectrum analysis typically provides reliable preliminary results for users' reference.

04. Can AI spectrum analysis analyze metal samples?

AI spectrum analysis can handle the analysis of metal samples. It not only supports the fitting of free radical samples but has also been optimized specifically for metal complexes and multi-component systems. Therefore, the analysis of metal samples, especially those involving paramagnetic metal ions, falls within its capabilities. However, the precision of the results may vary depending on the specific metal and sample complexity.

05. Does AI spectrum analysis support EPR instruments from other brands?

Currently, the AI spectrometric system is not compatible with direct integration and usage of EPR spectrometers from other brands. The current system only supports EPR spectrometers from CIQTEK.

06. If a sample is more complex, such as multi-component with coupling between components, can AI still be used?

For complex samples with multiple components and coupling between them, AI spectrum analysis can certainly provide significant assistance. Leveraging its rich data and intelligent algorithms, it can partially differentiate and identify components, even in the absence of extensive experiential knowledge. AI spectrum analysis can provide analysis results to help users quickly understand the main features in the spectra.

07. What is the reliability of AI analysis, and can the analysis results be included in the platform's testing reports?

In most cases, AI spectrum analysis has a high level of reliability, especially for common free radicals and metal samples, where the accuracy of the results can exceed 90%. The results can provide reliable references for preliminary analysis. However, due to the complexity of spectra and the diversity of samples, in a very small number of cases involving high complexity and coupling, AI analysis results may require further manual confirmation. Therefore, it is recommended to include AI-assisted analysis results as supplementary data in formal testing reports, explicitly stating that it is analyzed with AI to ensure the scientific rigor and validity of results.
