Article Synopsis
- Smokeless powders (SLPs) consist of thermolabile and non-thermolabile compounds, and their analysis using GC-MS (Gas Chromatography-Mass Spectrometry) can be significantly influenced by the conditions during injection, but no systematic studies had been previously conducted.
- A recent study examined how the type of injector liner and the inlet temperature affect the chemical profiles of SLPs, revealing that both factors are crucial for obtaining reliable results, with the liner type having a notable impact.
- Interestingly, while higher temperatures led to the degradation of some thermolabile compounds like nitroglycerin, these extreme conditions actually resulted in more consistent measurements, suggesting that contrary to prior beliefs, harsher conditions might be more beneficial for profiling.
