The Use of the Sample Spectrum for Assessing the Impact of Different Stages of the NPKS Fertilizer Preparation on the Results of X-Ray Fluorescence Analysis
Abstract
A key feature of the analytical control in industrial production is a constant striving for automation and shortening of the time of analysis. Optimization of the sample preparation which is the most time-consuming and inaccurate stage of any chemical analysis is first required to achieve the goals. The case study of NPKS-fertilizer using x-ray fluorescence analysis (XF) is presented to assess different methods of sample preparation. A matrix «object - characteristic feature» is compiled for NPKS fertilizers and most informative indicators are specified for ranging analysis of the particles in size in pressed sample. The line intensities of middle (by atomic mass) elements, potassium in particular, are considered the most informative features for this purpose. Statistical indices are calculated for each type of sample preparation.
