Use of solid sampling Zeeman atomic absorption spectrometry (SS-ZAAS) for certification purposes

Atomic Absorption, Atomic Emission, and Flame Emission Spectrometry

“…A similar linear relationship was seen when the ratio of peak height to analyte mass was plotted against the analyte mass. Evaluation of this calibration method (397) showed it to be less accurate than the method of standard additions and the use of matrix-matched solid standards, but it was satisfactory for some applications. Minami et al (398) reported on the use of a threepoint estimation standard addition method of calibration for the determination of Cr in powdered biological samples.…”
