[Simultaneous determination of three components in antongding injection by Kalman filtering method].


PMID 12953589

Abstract

Kalman filtering method was applied to determine three components in antongding injection without separation. The average recovery and relative standard deviation of amidopyrine, phenazone, barbital obtained by Kalman filtering method were 99.8%, 0.93%, 99.7%, 0.82%, 99.7%, 1.5% respectively. It was showed by t-test that there was no significant difference between the results of Kalman filtering method and standard method.
