Objective To study the joint application of multiple quality control charts in the determination of total arsenic content in rice. Methods The parameters of the quality control chart were analyzed and calculated by collecting the total arsenic content in rice. Multiple quality control charts were drew and the effects of the joint application were analyzed. Results The test results of total arsenic in rice were controlled by several quality control charts. An early warning response mechanism were established to quickly find the problem. Conclusion The joint application of multiple quality control charts provides the basis for the management and assessment of laboratory technical factors.
