Abstract

Two different approaches to enable on-demand preparation of controlled "contaminated" samples for evaluating cleaning techniques have been investigated using gravimetric weighing of mass artefacts and x-ray photoelectron spectroscopy on surface samples. The first method heated oil within a glass chamber to contaminate artefacts and the second method used an inverted magnetron vacuum gauge in a vacuum chamber to contaminate artefacts. Both methods applied a suitable controlled quantity of contamination to the surface of mass artefacts but the heated oil method also increased the surface temperature of the artefacts which may have an adverse effect on the surface properties.
