Liquid Extraction Surface Analysis Mass Spectrometry (LESA-MS): Examples of a New Surface Probing Technique for Clinical and Pre-Clinical Applications

Executive Summary:

• LESA and LESAplus liquid chromatography provide novel surface analysis tools for the spatial resolution of analytes from a wide variety of surfaces.
• Whole body or organ sections in particular can be probed for small molecules, lipids and proteins with a resolution of 400 – 1000μm.
• Commercial solution allows for automated processing of samples (Advion TriVersa NanoMate^® LESA^®).
