| Summary: | Charles University in Prague Faculty of Pharmacy in Hradec Králové Department of Analytical Chemistry Consultant: Doc. RNDr. Dalibor Šatínský, PhD. Diploma Thesis Title: The method development for determination of diazodinitrofenol explosive A new HPLC method for determination of diazodinitrophenol alongside with sodium picramate was developed and optimized. Column Ascentis® Express C18 10cm x 3mm; 2.7µm particles was select as most suitable one. Detection of compounds was performed at 220 nm using UV detector. Mobile phase consist of mixture 0.085% H3PO4 and acetonitrile in ratio 70/30. Flow rate was determined at 0.8 ml/min. Column oven temperature was set to 50řC. Retention times under these condition was tDDNP=1.324 min a tPikNa=4.012 min. Keywords: determination, diaziodinitrophenol, sodium picraminate, HPLC, chromatography, dinol, DDNP
