Abstract
A method for analysis of residual azide in an organic matrix (triazole derivative) is described. The azide was separated from the matrix using a solid phase extraction cartridge, and analyzed using reversed-phase chromatography with direct UV detection. The analysis of azide was used as a limit test for a level of 20 ppm relative to the weight of the organic matrix. Thermodynamic studies of the chromatographic system suggested that the interaction between azide and the stationary phase was hydrophobic in nature.
