Standardisation of elemental analytical techniques applied to provenance studies of archaeological ceramics: an inter laboratory calibration studyElectronic supplementary information (ESI) available: five tabular appendices giving element concentrations measured in reference materials. See http://www.rsc.org/suppdata/an/b1/b109603f/

Merits and limitations of layered and ion implanted specimens as possible reference materials to calibrate spatially resolved analytical techniques are discussed and illustrated for the case of gold analysis in minerals by means of x-ray spectrometry with the EPMA. To overcome the random heterogeneities of minerals, thin film deposition and ion implantation may offer an original approach to the manufacture of controlled concentration/ distribution reference materials for quantification of trace elements with the same matrix as the unknown.In order to evaluate the accuracy of data obtained by EPMA we have compared measured and calculated x-ray intensities for homogeneous and heterogeneous specimens. Au Lα and Au Mα x-ray intensities were recorded at various electron beam energies, and hence at various sampling depths, for gold coated and gold implanted specimens. X-ray intensity calculations are based on the use of analytical expressions for both the depth ionization Φ (ρz) and the depth concentration C (ρz) distributions respectively.

Tin (Sn) is one of the causative elements of the environmental pollution. As no certified reference materials for Sn are presently available, existing reference materials were analyzed for Sn by two independent analytical techniques; atomic absorption spectrometry (AAS) and neutron activation analysis (NAA). The results obtained by both methods were in agreement except for mixed diet which contains Sn in the range of 50 μ g/g. Further, tin concentrations in human and animal organs have been examined by AAS. Among organs tested tin concentrations in testes were the highest, 2.08±0.62 μ g/g dry weight (mean ±SD, n=12) in humans, and 1.45±0.55 μ g/g (n=8) in mice.

ABSTRACTOutstanding information about the material composition and pictorial techniques of the New Spain Colonial painting can be obtained via a full characterization using a set of analytical techniques. Given the cultural importance of this painting, a non-invasive approach is preferred. Moreover, the preparation and use of reference materials using original recipes is necessary for a correct interpretation of the spectroscopic data from historical objects. Here, we present the results obtained via an in-situ Raman spectroscopic analysis of a set of pictorial reference materials, created according to XVI and XVII centuries’ recipes. Several difficulties were encountered, such as the low Raman detection signal, an intrinsic fluorescence of the material, and in some cases even laser-induced degradation. For this reason, the usual molecular Raman analysis was extended to Surface Enhanced Raman Spectroscopy (SERS), which enhances the Raman signal and quenches the fluorescence. It was then applied to the analysis of two wood paintings from the ex-convent San Francisco Tepeyanco, in Tlaxcala.

Radioisotope x-ray fluorescence analysis was performed to determine normalized elemental intensities for pre-Columbian sherds and roller stamps from different archaeological sites in the Middle Orinoco region of Venezuela. These normalized intensities were used to construct three-component (Triangle) graphs separating the sherds into three groups based on their known origin. The three-component graphs were: (Zn, Sr, Zr), (Rb, Sr, Zr), and ( A, Sr, Zr), where A = Cu + Zn + Pb normalized intensities. The total precision was shown to be better than 5% absolute for all cases studied. It was concluded that two of the roller stamps found at one site were probably manufactured in a different source area. This lends support to the notion that the roller stamps were a trade item in late pre-Columbian times (1000–1400 A.D.). The method applied in this study using a 109Cd (2 mCi) source seems to be appropriate for provenance studies of archaeological ceramics where many samples are processed, because it has the inherent advantages of being simple, economical, and rapid.

Geological Materials

The majority of analytical techniques, aimed at establishing the mercury contents of geological materials, require comminution of samples prior to analysis. This typically involves a process of crushing, followed by milling. It is known that heat is generated during milling in conventional milling apparatuses; therefore mercury losses may be expected due to the element’s volatility. To investigate mercury losses during milling, we analysed the mercury contents of nine certified reference materials of igneous rocks before milling and after respectively 3 and 10 minutes of milling, using a direct mercury analyser. The results of the experiments suggest that: (1) mercury losses are insignificant after 3 minutes of milling, (2) mercury losses become significant when samples undergo excessive milling, (3) mercury losses do not appear to be mineralogically controlled and (4) for samples with low mercury contents, contamination during milling plays a much more significant role in the analysed mercury contents than milling time.
