Application Note: Detection of Trace Contamination on Metal Surfaces using the Handheld Agilent 4100 ExoScan FTIR
1 July 2013
Efficient adhesive bonding of metal surfaces requires a high level of cleanliness of the surfaces. The 4100 ExoScan FTIR with a grazing angle sample interface enables identification and quantification of metal surface cleanliness in the field. After the metal has been cleaned, the analyzer can be used to detect the presence of organic and some inorganic contaminants. Even very low amounts of contamination can severely decrease the ultimate bond strength; the highly sensitive 4100 ExoScan can detect trace levels of contaminants.
