[Gas chromatographic method for estimating chemical stability of nitroquanidine propellant]

This paper describes a GC analytical method for nitroquanidine propellant instead of the tranditional methylviolet method. Operating conditions were as follows: TDX-01 packed column, 150-200 mesh, 800 mm x 3 mm i.d., at 150-170 degrees C with TCD. Released gases, CO2 and N2O contents in a sealed vessel packed with nitroquanidine were calculated according to the normalization of corrected peak areas of air, CO2 and N2O. Thus, the change in the chemical stability of nitroquanidine during the period of storage and thermal aging could be observed.
