Abstract

In this study the main objective was to develop and demonstrate a glow discharge microplasma coupled to a miniature spectrometer for detection of fire signatures from pyrolyzing and burning spacecraft materials. Our experimental results demonstrated plasma-based detection of the combustion-produced carbonaceous aerosols. Demonstrating versatility for chemistry analysis, the plasma detector could distinguish carbonaceous aerosols with different C/H ratios and recognize inorganic samples such as salts and metal oxides from carbonaceous aerosols. In-situ analysis of aerosol samples validated the microplasma's analytical utility by linearity of its optical emission intensity with aerosol elemental composition.
