TY - CONF A1 - Kjaervik, Marit T1 - Quantitative biocide profile measurements by calibrated XPS N2 - This presentation provides an update on recent results from quantitative XPS-measurements of real and artificial biofilms. NAP-XPS, lab-based XPS and synchrotron-based XPS was used to obtain a vertical concentration profile of iodine in agarose-films with information depth ranging from 1 to 18 nm.

Various model systems of biofilms have been developed and characterised at synchrotron- and lab-based facilities. By obtaining the chemical composition at various information depths, the vertical distribution of iodine in an artificial biofilm have been determined.
