Researchers from Justus-Liebig University in Giessen, Germany have now recognized that when surgeons are using electric cautery, the smoke that's released contains information about what is being cut. By using a mass spectrometer attached to the smoke collecting vacuum, the scientists are hoping to develop a technology that will provide almost real time, clinically useful information about the tissue under the knife.
