Combination of Total-Reflection X-Ray Fluorescence Method and Chemometric Techniques for Provenance Study of Archaeological Ceramics.

The provenance study of archaeological materials is an important step in understanding the cultural and economic life of ancient human communities. One of the most popular approaches in provenance studies is to obtain the chemical composition of material and process it with chemometric methods. In this paper, we describe a combination of the total-reflection X-ray fluorescence (TXRF) method and chemometric techniques (PCA, k-means cluster analysis, and SVM) to study Neolithic ceramic samples from eastern Siberia (Baikal region).

Features of sample preparation techniques in the total-reflection X-ray fluorescence analysis of tea leaves.

Tea is a popular drink around the world and contains essential minerals and trace elements for human health. In this study, the analytical capabilities of the total-reflection X-ray fluorescence method (TXRF) were considered for the analysis of tea. Different sample preparation techniques, e.

Development and validation of a method for multielement analysis of apatite by total-reflection X-ray fluorescence spectrometry.

Apatite group of minerals incorporates a large range of trace metals such as Sr, Y, U, Th, as well as the rare earth elements, that allows obtaining useful information on their genesis and could be used in several applications in geology and geochemistry. In this study, a new method for the multielement analysis of apatite using total-reflection X-ray fluorescence spectrometry (TXRF) was developed. The acid digestion procedure was chosen as an optimal sample preparation with the capability to analyze a low sample amount (~5-10 mg).
