  • Direct impact ionization (DII) mass spectrometry
    Patent number: 8704169
    Abstract: Disclosed is a mass spectrometer for analyzing a sample that has or is suspected of having microorganisms. The disclosed mass spectrometer has been uniquely configured to include a sample platform which functions as a counter electrode or discharge electrode and a surface to provide the sample to be analyzed. The mass spectrometer also includes an ion source positioned adjacent to the sample platform for ionizing and volatizing molecules within the sample, wherein the sample platform and the ion source are positioned such that during operation of the mass spectrometer an electrical discharge takes place between the ion source and the sample platform. Also disclosed are methods for generating a mass spectrum profile/fingerprint of a sample. The methods include positioning a sample platform having a sample adjacent to an ion source.
