Abstract: In this investigation, samples of whole bovine milk were diluted with water-soluble tertiary amines solution and introduced in two axially viewed inductively coupled plasma optical emission spectrometer (ICP OES) instruments equipped with different interfaces (shear gas and end-on gas interface). The accuracy and the Mg II (280.2 nm)/Mg I (285.2 nm) ratio were evaluated. Higher values for Mg II/Mg I were observed with the shear gas interface. However, these values were less affected by changes of instrumental parameters when using the end-on gas interface. Results with suitable accuracy were obtained for a certified reference material of powdered whole milk (NIST SRM 8435) using instruments equipped with each interface. (C) 2004 Elsevier B.V.
