XPS spectra of HS(CH_2)_15 COOH terminated a self assembled monolayer (SAM)sample was collected over a period of 242 minutes to determine specimen damage during long exposures to monochromatic Al Ka x-rays. For this COOH terminated SAM we measured the loss of oxygen as a function of time by rastering a focused 100 W, 100 um diameter x-ray beam over a 1.4 mm x 0.2 mm area of the sample.
