NO. Title AA79 Analysis of trace elements in steel JIS G1257 “Iron and steel-Methods for atomic absorption spectrometric analysis” is defined as an official method for analyzing the metals in steel. Furthermore, an analysis method that employs electrothermal atomic absorption spectroscopy of Sb, As, Al, Sn, and Se was added as a supplement in March, 2000. For the analysis of As, Al, Sn, and Se, the matrix matching method is specified by JIS G1257 to avoid interference from a large number of matrix in steel samples. This analytical method dissolves pure iron of the same quantity as a steel sample, adds a known amount of a target element, and makes a calibration curve. Moreover, a standard addition method that adds a known amount of a target element to a dissolved steel solution to make a calibration curve is used for the analysis of Sb. This standard specifies the background correction of the Zeeman method to avoid spectral interference, when As, Al, Sn, and Se are analyzed with the matrix matching method. Since the Model Z-2000 Polarized Zeeman Atomic Absorption Spectrophotometer employs the polarized Zeeman background correction method, the baseline is stable. In this experiment, the Sb, As, Al, Sn, and Se of a steel sample are analyzed with a Model Z-2000 Polarized Zeeman Atomic Absorption Spectrophotometer, according to the JIS G1257. * Refer to ‘TECHNICAL DATA AA sheet No. 69’ for details regarding the polarized Zeeman background correction method  Model:Z-2000 AA78 Analysis of potassium in fertilizer by atomic emission spectrometry Model:  Z-2000 Keywords: AA, Atomic Emission Spectrometry, Fertilizer, K AA77 Determination of cadmium in soil sample after pretreatment by chelate solid-phase extractant Model:  Z-2000 Keywords: AA, Graphite Furnace, Enviroment, Soil, Cd, Chelate solid-phase extractant, NOBIAS AA76 Determination of Pb in aluminum foil by polarized zeeman atomic absorption spectrometry Model:  Z-2000 Keywords: AA, Aluminum foil, Pb AA75 Analysis of trace elements in semiconductor manufacture reagent by polarized zeeman atomic absorption spectrophotometer Model:  Z-2000 Keywords: Semiconductor manufacture reagent, trace elements, GAAS, ZAA AA73 Analysis of arsenic in foods by zeeman correction atomic absorption spectrophotometer with hydride formation system Model:  Z-2000 Keywords: AA, Foodstuff, As, Hydride formation system AA72 Pnalysis of arsenic in foods by zeeman correction atomic absorption spectrophotometer with hydride formation system Cd and Pb in polyethylene materials (Applied analysis for RoHS, WEEE) Model:  Z-2000 Keywords: AA, GA, The environment, RoHS, WEEE, Pb, Flame, Cd AA71 Analysis of silicon in oil by gfaas method Model:  Z-2000 Keywords: AA, Modifier, Oil, Si AA68 Analysis of cadmium and lead in plastic by AAS (Applied analysis for RoHS AND WEEE) Model: Z-5010 Keywords: AA, Plastic, Pb, Cd, AA67 Analysis of Calcium, Iron and Sodium in gelatin by GFAAS Model: Z-5010 Keywords: AA, Gelatin, Ca, Fe, Na
