Objective: To establish a method for rapid screening of Cr elements in vacant capsule by X-ray fluorescence elemental technology. Method: X-ray fluorescence elemental analyzer,test time:180 s,standard deviation:1 σ,mode:plastic mode. Results: Under these conditions,the detection limit was 0.01‰,the detection rate of positive sample exceeding 0.01‰ was 97.8% compared with the result of atomic absorption spectrometry. Conclusion: The method is simple and rapid,it can be used for the rapid screening of Cr elements in vacant capsule.
