Abstract
The goal of this research was to establish feasibility of determination and quantification of lead in the raw mixed materials for cosmetic applications by synchrotron radiation induced X-ray fluorescence (SR-XRF). The penetrating properties of X-rays, allow to measure the samples as delivered with minimal intervention in the sample material and no need for any pre-treatment processes. The established quantification scheme has been based on the emission-transmission experiment. The measurements have been done at multimodal PolyX beamline of Solaris National Synchrotron Radiation Centre in Krakow, Poland. Apart of the samples reference materials with similar lead content have been analysed, with the recovery values in range of 67 % to 133 % achieved. We have determined the detection limits for the lead content at μg/g level for only few minutes of acquisition in a relatively complex matrix of sample material. The obtained result implies that the SR-XRF station can be effectively used for quality control and efficient screening of hundreds of samples of cosmetic materials in a short acquisition times.
