摘要: Abstract The chemical composition of ancient metal objects provides important information for manufacturing studies and authenticity verification copper or bronze artifacts. Non- minimal-destructive analytical methods are preferred to mitigate visible damage. Laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS) enables the determination major elements as well impurities down lower ppm-levels, however, accuracy precision analysis strongly depend on homogeneity reference materials used calibration. Moreover, appropriate procedures required e.g. in terms strategies (scan mode, spot size, etc.). This study reviews available alloy (certified) — (C)RMs from different sources contributes new metallurgical data spatial elemental distribution. Investigations standards were performed by optical scanning electron microscopy with X-ray (SEM-EDX) following materials: NIST 454, BAM 374, 211, 227, 378, BAS 50.01-2, 50.03-4, 50.04-4. Additionally, influence inhomogeneities calibration is evaluated define an optimum strategy line scan versus single ablation, variation selection most RMs minimum number materials.
