Analysis of Nitrogen in Fertilizer Using ICP-OES With Dual Side-On Plasma Observation

Nitrogen plays a critical role in modern fertilizer formulations. Accurate nitrogen determination supports product quality, regulatory compliance, and efficient nutrient management. Reliable elemental analysis helps laboratories verify fertilizer composition, monitor production consistency, and reduce the risk of under- or over-fertilization. This application report demonstrates a practical approach for fast and dependable nitrogen analysis in fertilizer samples using the SPECTRO ARCOS ICP-OES, which combines dual side-on plasma observation with advanced optical performance to support this task.

The report presents a method based on ICP-OES with dual side-on plasma observation for the determination of nitrogen in fertilizers. Calibration with ammonium nitrate, excellent linearity, and recoveries close to 100% for a certified reference material demonstrate the robustness and accuracy of the approach. Multiple nitrogen emission lines in the extended UV range provide analytical flexibility while helping to minimize spectral interferences. This makes ICP-OES a strong choice for routine fertilizer testing and quality control workflows that require reliable elemental analysis results.

Key Benefits
  • Obtain fast and accurate nitrogen determination for fertilizer quality control.
  • Streamline routine fertilizer analysis and achieve high analytical confidence.
  • Benefit from multiple nitrogen emission lines that support analytical flexibility and interference reduction.
