Inverse gas chromatography (IGC) was used to characterize dispersive surface energies γ S D and cohesive Hamaker constants A ii for RDX, PETN, TNT, ammonium nitrate (AN), and AN‐based explosives at 303 K. The γ S D for RDX at 303 K is compared to previous studies and generally found to be in good agreement, substantiating the use of NESTT training materials to characterize explosives via IGC. Additionally, the effect of the amount of fuel in the AN mixtures on γ S D is examined using simple linear regression. Finally, the IGC‐predicted A ii values are compared to Lifshitz estimations for A ii of RDX, PETN, TNT, and AN.
