Development of a Low‐Cost Method for the Determination of Stabilizers in Smokeless Propellants Using Thin‐Layer Chromatography and Image Densitometry

This work developed and evaluated a rapid, cost‐effective, and mobile analytical method for the quantification of stabilizers in nitrocellulose‐based propellants, using thin‐layer chromatography and image densitometry. The method demonstrated effectiveness in the separation and quantification of diphenylamine and N‐nitrosodiphenylamine, showing linearity, accuracy, and precision for concentrations above 0.3 wt%. To address limitations at low concentrations, a screening test approach with a cutoff value of 0.3 wt% was proposed. Innovations included a custom‐built dark chamber to improve photographic records, and a custom script for automated image analysis, using open‐source software. The developed analytical procedure, along with the supporting tools created, offers a promising solution for rapid and efficient field monitoring of nitrocellulose‐based propellant stability, with the potential to complement existing laboratory methods in ammunition surveillance.
