Analysis of stabilizer and stabilizer degradation products in nitrocellulose based propellants was done using high-performance liquid chromatography (HPLC) with photodiode array (PDA) detection. Analysis of these compounds was done in less than 12 minutes using an isocratic mobile phase. Using PDA detection provided the capability of monitoring at several different wavelengths as well as providing UV spectra which could be used to assess peak purity and match the spectra against known library spectra.
