Simultaneous analysis of diphenylamine and its derivatives by high performance liquid chromatogrphy

DPA and its derivatives always are present in propellants. They are very important components of propellants due to being quality measure of propellants. By the experimental study an analytical method based HPLC-DAD was established to determine simultaneously these compounds. All standard plot equations or standard plots of the HPLC peak area versus concentrations of DPA or its derivatives such as NO-DPA, 2- nitro –DPA, 2,4’- dinitro- DPA, 4,4’- dinitro- DPA were established. Besides, the values of LOD, LOQ of method were determined from standard plots too.
