Abstract:

For generalizing a method for treating reagent cross contamination problems through the principle of sequence detection,the article provides several representative solutions,including the solutions about contamination bringing into cuvette by the continuous use of sample and reagent needles,contamination using same cuvette among different determinations and contamination from washing system. The contamination sources are screened as the order of the pollution above. Statistical analysis for interference is performed for verifying the feasibility of this method.
