    Homogeneity Test of Elemental Content in Agricultural Soil Reference Material Candidate Using ICP-MS
    (Napata College, 2024-12) Mohammed Salah Eldeen Elagib; Mohamed. A. H Eltayeb; Abu baker Mustafa Idreas
    The aim of any analytical measurement is to obtain accurate, reliable, and consistent data. Certified Reference Materials (CRMs) are vital in obtaining reliable results in various analytical fields such as environmental and medical studies. This paper discusses the production of an agricultural soil CRM candidate from the Al-Ahsa region, Saudi Arabia, using an ICP-MS instrument. The CRM is intended to be applied for quality assurance of toxicological and environmental analyses of soil matrices for some elements at macro, micro, and trace levels. This article demonstrates homogeneity tests as an essential parameter for CRMs. A one-way Analysis of Variance (ANOVA) was used to assess the between-bottle homogeneity at a confidence interval of 95%. The p-values of all elements in this CRM candidate are > 0.05, indicating no significant variation in elemental concentration.
