Abstract: Mass spectrometry is a very versatile and important technique in analytical chemistry. From atomic bombs to Alzheimer’s disease, after a century of improvements and developments there are now countless applications for mass spectrometry in research and industry. One important branch within the field is imaging mass spectrometry as it combines chemical and location specific information. Lipids, the main building blocks of cell membranes, are found in all living, cellular organisms. They are a d... more
