Determination of Ethyl Centralite Stabilizer in a Double-Base Propellant
by Gas Chromatography: Linearity, Accuracy, Precision
Ljiljana Jelisavac
Linearity, accuracy and precision of the gas chromatography determination of ethyl centralite contents in double-base propellant samples, were investigated. Different kinds of calibration curves were generated and the linear detector range for ethyl centralite was determined. By comparing of different calibration procedures the single point calibration was chosen as an optimal calibration method of the gas chromatography determination of ethyl centralite contents in double-base propellants, but some revisions related to the preparation of ethyl centralite standards and samples were needed. The accuracy of the results and the precision of the gas chromatography method were verified. This method was applied for the determination of the stabilizer contents in the double-base propellant, Plamen D, which was artificially aged until the stabilizer content becomes equal to zero.
Key words: explosive materials, double base propellant, stabilizer, ethyl centralite, gas chromatography.
