[0040] Explanation of terms:
[0041] Mass Spectrometry: A method in which moving ions are separated according to their mass-to-charge ratios by electric and magnetic fields and then detected. Substances can be identified by their mass-to-charge ratios.
[0042] Mass spectrometry imaging technology: Mass spectrometry imaging is an imaging method based on mass spectrometry technology. This method directly scans biological samples for imaging through mass spectrometry, and can simultaneously analyze the spatial distribution characteristics of hundreds of molecules on the same tissue slice or tissue chip. In simple terms, mass spectrometry imaging technology is a method of imaging with the help of mass spectrometry, coupled with the control of specialized mass spectrometry imaging software, using a mass spectrometer that analyzes the standard molecular weight of biomolecules by determining the mass-to-charge ratio.
[0043] Extraction: Extracting a substance using an extractant. ...
