Abstract:A mathematical model on mixed sample detection of chemical samples was developed. The detectable rate of positive samples was proposed as precondition for mixed sample testing. The results showed that the mixed sample testing might be preformed when the detectable rate was less than 30.8%. Combined with method detection limit and regulation limit, the best mixed sample number was determined. This model established is suitable for the detection of chemical substances in chemical samples, which can improve the detection efficiency and save test costs.
