Scanning Electron Microscopy


Laser microprobe mass analysis with the commercial LAMMA-500 (transmission type) instrument when utilized in laser desorption conditions provides information which allows the identification of particular asbestos varieties, in various types of samples, including lung tissue. Also it has detection capability of adsorbed organic material and it is a valuable tool for the study of the surface of chemically modified asbestos fibers manufactured by silanation or through phosgene treatment (chrysophosphate). Recent progress within our laboratory is discussed, and shortcomings of the methodology are indicated.
