The method validation covers parameters such as linearity, limit of detection (LOD), limit of quantification (LOQ), trueness, repeatability, intermediate precision and robustness. A calibration curve covering the whole working range was achieved with coefficients of determination typically higher than 0.9992. The repeatability of the method (RSDrep) was 0.5 %, and the intermediate precision was 2.3 % at the target mass fraction of 20 ng/kg. Moreover, the method was robust with respect to the salinity of the seawater. The limit of quantification was 2.7 ng/kg, which corresponds to 13.5 % of the target mass fraction in the future certified reference material (20 ng/kg). An uncertainty budget for the measurement of mercury in seawater has been established. The relative expanded (k = 2) combined uncertainty is 6 %. The performance of the validated method was demonstrated by generating results for process control and a homogeneity study for the production of a candidate certified reference material.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Development and validation of a method for mercury determination in seawater for the process control of a candidate certified reference material","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Mercury; Water Framework Directive (WFD); Seawater; Inductively coupledplasma mass spectrometry (ICP-MS); Method validation; Uncertaintyestimation","OtherDescriptors":null,"Notes":null,"AnaPub":2015,"MonPub":null,"DateUpdate":"2016-06-07","DateCreate":"2016-05-29","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000358646400030","VABBcode":null,"OpenAcc":1,"DOI":"10.1007/s00216-015-8833-9"},"refs":null,"anarec":{"AnaID":256933,"PubliDate":2015,"Pagination":"6569-6574","XtraPublOfAnaID":null,"ISBN":null,"Volume":"407","Issue":"21","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":65810,"SerRR":"Analytical and Bioanalytical Chemistry.
