Stable cesium isotope contained in Soya Bean Flour Certified Reference Material (INCT-SBF-4) was analyzed. This sample contains 129.1±4.3 ng/g (certified value) of cesium. 852.1 nm, the measurement wavelength for cesium, is in the long wavelength region where BKG correction is not possible by the deuterium lamp correction method due to the low light intensity of a deuterium lamp. However, the polarized zeeman correction method allows the correction at any wavelengths. 

The analysis value agreed with the reference value, indicating that the procedure from the preparation to the measurement was performed accurately.
