Abstract A two-part single-laboratory validation study was conducted for determination of the P and K content in commercial fertilizer materials by inductively coupled plasma-optical emission spectrometry (ICP- OES). While several methods exist for determination of P and K in fertilizer products, the main focus of this study was on ICP-OES determination, which offers several unique advantages. Fertilizer samples with consensus P and K values from the Magruder and Association of Fertilizer and Phosphate Chemists (AFPC) check sample programs were selected for this study. Validation materials ranging from 4.4 to 52.4% P2O5 (1.7 to 22.7% P) and 3 to 62% K2O (2.5 to 51.5% K) were utilized. Because all P and K compounds contained in fertilizer materials are not "available" for plants to use, this study was conducted in two parts. Part A focused on ammonium citrate–disodium EDTA as the extraction solvent, as it estimates the pool of fertilizer P and K that is considered available to plants. Part B focused on hydrochloric acid as the digestion solvent, as it estimates the total P and K content of the fertilizer product. Selectivity studies indicated that this method can have a high bias for fertilizer products containing sources of phosphite or organic P compared to gravimetric or colorimetric methods that measure just orthophosphate. Provided the analytical challenges outlined in this study are addressed, this method offers the potential for a quick, accurate, and safe alternative for determining the P and K content of commercial inorganic fertilizer materials.

This work deals with method validation for regulated metals (Cd, Pb, Ba, Sn, Cr and Cu) determination in infusion and transfusion medical devices. The investigated metals were extracted with water at (37 ± 1) °C followed by their determination in the extract by using inductively coupled plasma optical emission spectrometry (ICP-OES). The validated method was applied in the analysis of infusion and transfusion devices commercialized in Brazil to verify compliance with current legislation, which establishes that the sum of Pb, Ba, Sn, Cr and Cu in the extract must not exceed 1 mg L-1 and that of Cd must not 0.1 mg L-1. Samples from five manufacturers of infusion and transfusion devices, produced in Brazil or imported, were analysed. The results of the analysis showed that all devices complied with the legislation, whereas the sum of Pb, Ba, Sn, Cr and Cu concentrations and that of Cd in the extract were lower than the maximum permissible; Cd was not detected in any sample extract and the sum of the other elements was < 0.14 mg L-1 in all extracts of the analysed samples.
