How to Search for Chemical Biosignatures on Ocean Worlds

We describe how to optimize the search for organic chemical biosignatures during in situ missions to ocean worlds. This requires sample ingestion, liquid sample handing, separation science, and detection using mass spectrometry and other optimized detectors. Inorganic chemical analysis is also essential to provide sample context information.
