  • Downhole mass spectrometry
    Patent number: 9274248
    Abstract: A method comprising using a first mass analyzer of a downhole tool to isolate specific ions within a sample received in the downhole tool, using a second mass analyzer of the downhole tool to stabilize the ions isolated by the first mass analyzer, and using a third mass analyzer of the downhole tool to catalog the stabilized ions.
