Application Note: Detection of Trace Contamination on Metal Surfaces using the Handheld Agilent 4100 ExoScan FTIR
8 March 2013

Efficient adhesive bonding of metal surfaces requires a high level of cleanliness of the surfaces. Even very low amounts of contamination can severely decrease the ultimate bond strength. In this application note it is demonstrated that the Agilent 4100 ExoScan FTIR system, equipped with grazing angle sample optics, can provide the level of sensitivity required for the detection and identification of a large number of organic and inorganic contaminants on metal surfaces.
