10 Questions
What is the main purpose of mass spectrometry imaging (MSI)?
To visualize the spatial distribution of molecules based on their molecular masses
How is mass spectrometry imaging (MSI) performed?
By collecting a mass spectrum at different spots as the sample is moved
What does the mass spectrum collected during mass spectrometry imaging (MSI) help to map?
The spatial distribution of a compound pixel by pixel
What type of data does mass spectrometry imaging (MSI) generate?
