Determination of Bacterial Endotoxin in Iodixanol by Kinetic Turbidimetric Method / 中国药师

Objective:To establish a method to determine the content of bacterial endotoxin in iodixanol. Methods:The standard curve of kinetic turbidimetric method was established and the dilution ratio was optimized by interference test. Bacterial endotoxin in the samples was determined. Results:The dilution ratio of 1 ∶12 did not interfere with the test. The recovery rate of bacterial endotox-in was 50%-200%. Conclusion:The kinetic turbidimetric method is suitable for the determination of bacterial endotoxin in iodixanol.
