  • Title: [Study on the method for determination of analgin using flow injection spectrophotometry].
    Author: Liu WZ, Wang CD, Chen H.
    Journal: Yao Xue Xue Bao; 1993; 28(4):317-20. PubMed ID: 8213178.
    Abstract:
    A new flow injection spectrophotometric method for the determination of analgin has been developed. The main factors which affect the determination were investigated. The absorption maximum is 650 nm. Under optimum conditions the calibration graph is linear in the range of 0.2-3 mg/ml, the average recovery is 99.8% with a relative standard deviation of 0.5%. The proposed system permits the analysis of about 240 samples per hour and has the advantages of analytical efficiency, sensitivity and accuracy for the determination of analgin.
