węgiel/warstwa węglowa z zanieczyszczeń przypadkowych Explanation: I have not seen "węgiel przypadkowy" - the literal translation. Here is one source that fails to translate the word: Calibration of the binding energy scale was done by assuming the position of the adventitious C 1s line of C-C and C-H bonding at 284.6eV. Kalibracji energii wiązania dokonano dla wartości C 1s wynoszącej 284.6eV w wią- zaniach C-C i C-H. http://www.biomat.krakow.pl/gazeta/archiwum/89-91F.pdf |

Reference: Adventitious Carbon Reference information: What is Adventitious Carbon? A thin layer of carbonaceous material is usually found on the surface of most air exposed samples, this layer is generally known as adventitious carbon. Even small exposures to atmosphere can produce these films. Adventitious carbon is generally comprised of a variety of (relatively short chain, perhaps polymeric [1]) hydrocarbons species with small amounts of both singly and doubly bound oxygen functionality. The source of this carbon has been debated. It does not appear to be graphitic in nature and in most modern high vacuum systems vacuum oils are not readily present (as they have been in the past) [1,2,3,4]. There may be some evidence that CO or CO2 species may play a role in the gradual appearance of carbon on pristine surfaces within the vacuum of the XPS chamber [3].
