Sample preparation techniques for detecting organic fertilizer using X-ray fluorescence analysis
Organic fertilizer samples, after undergoing specific pre-processing, are rapidly analyzed (within 50 seconds) for P, K, Ca, Mg, Zn, Cu, and other elemental contents using a handheld X-ray fluorescence (XRF) analyzer. The XRF results demonstrate high correlation and accuracy with the laboratory standard ICP-OES method. This technology enables compost sites to quickly assess nutrient levels, mitigating the risk of products exceeding copper and zinc regulatory limits, thereby ensuring effective quality control of organic fertilizers.
