Abstract
Among several types of mass spectrometers currently developed and used, Matrix Assisted Laser Desorption/Ionization Time Of Flight Mass Spectrometer (MALDI-TOF-MS) is picked up and reviewed in this paper. It can be applied for various samples in material science, including insoluble species. And further, materials can be measured and evaluated directly from industrial components in which the materials are used. Therefore its availability for industrial R & D or failure analysis processes is considered to be significant. And an application of MALDI-Imaging for material evaluation is introduced. It is a technology to visualize the molecular weight distribution in 2D samples.
