REVEALING THE TRUE CHARACTER...
Sputtered Neutrals Mass Spectrometry (SNMS) - a New Method for Quantitative Depth-Profile Analysis Homogeneity and chemical composition of different layers determine thequality of the new high-temperature superconductors. Accurate quantification of each individual layer is crucial. One by one, atomic layers are stripped away by ion bombardment.The resultant neutral particles can then be analyzed by theSSM 200 detection system. Only now is the true character revealed! In otherwords, the depth profile. Quantitatively! All made possibleby the SSM 200, whose modular construction can be adapted to both Leybold surface analysis or any other UHV system. Interested?
