  • Uncertainty evaluation and in-house method validation of the herbicide iodosulfuron-methyl-sodium in water samples by using HPLC [Elektronski vir]
    Drolc, Andreja ; Pintar, Albin
    A method for separation and quantitative determination of the iodosulfuron-methyl-sodium in water samples by using high performance liquid chromatography (HPLC) was developed and in-house validated. ... Surface and groundwater samples were used to demonstrate its selectivity, detection and quantification limits, linearity, trueness and precision. Method accuracy was quantified through measurement uncertainty estimate based on method validationdata. Our analytical protocol allowed us to quantify iodosulfuron-methyl-sodium in ground water and surface water in concentration level between 2.50 - 50.0 ìmol L-1 with satisfactory recoveries (99 % - 104 %)and repeatability lower or equal than 0.3 % for all the matrices. Measurement uncertainty of results was evaluated to be 4.0 % with 95 % confidence level.
