The paper presents a study on removal of possible interferences for the quantification of ⁹³Zr and ⁹³Mo using an ICP-MS/MS. ⁹³Zr and ⁹³Mo can be separated from each other and from the ⁹³Nb isobar with the reactive gas of ammonia. We propose a measurement scheme aiming at quantification of ⁹³Zr and ⁹³Mo in environmental samples collected in Fukushima Daiichi Nuclear power station.
