Mass Spectrometry of Spacecraft Contamination Using Direct Analysis in Real-Time Ion Source [link]Paper  doi  abstract   bibtex   
Spacecraft contamination was analyzed using mass spectrometry with the direct analysis in real-time ionization source. This source uses metastable helium for soft ionization and to mediate atmospheric desorption of samples into a mass spectrometer. The sampling methodology allows polymers to be assessed for the presence of vacuum labile components. Vacuum labile residues are significant sources of contamination on spacecraft optics, science instruments, and thermal control surfaces. The methodology also provides sensitive analysis of molecular contamination on spacecraft surfaces using existing spacecraft sampling procedures. This provides identification information for a wide range of molecular components including biomarker compounds. Read More: http://arc.aiaa.org/doi/abs/10.2514/1.A32613
