Nu Instruments | Evaluating Detector Linearity Across an Extended Dynamic Range
This application note demonstrates the linear performance of the Attom detector system across pulse counting, attenuated pulse counting and Faraday detection modes.
ICP-MS laboratories frequently analyse samples that contain both ultra-trace and major elements. Detector systems must therefore maintain linearity across a broad concentration range.
The Attom detector architecture combines multiple detection modes and automatic crossover calibration. A wide concentration range of standards was analysed to evaluate detector performance.
Calibration curves for multiple elements produced excellent linearity, with correlation coefficients exceeding 0.999. The study showed no significant non-linearity at detector crossover points.
Key Takeaways:
- Detector linearity maintained across multiple detection modes.
- Excellent calibration performance with R² > 0.999.
- Suitable for samples spanning wide concentration ranges.
