| As a prelude to online analysis, Potassium fertilizer samples are analysed using a laboratory rig. Russian, Belarusian and Israeli potash samples form the calibration/analysis sets. Calibration curves were constructed using the ratio of the intensity of key elements (Na, Mg, Ca) to intensity of K peaks. Results showed sufficient accuracy and precision for online analysis applications. | |||||
