In order to reduce the systematic uncertainties caused by the sequential injection in AMS measurement of ¹⁸²Hf, a technique for instantaneous monitoring of off-axis ∑HfF₅⁻ current was developed in the AMS laboratory at China Institute of Atomic Energy (CIAE). The stability and reliability of this method have been experimentally verified. As a result, the accuracy for AMS measurement of ¹⁸²Hf was significantly improved.
