Analysis of a Roman sword with the M4 TORNADO
Archeometric objects are unique and very sensitive to changes in their consistency. This must be taken into account when examining them. Their examination is necessary for the preparation of their restoration and for understanding the technologies of their manufacture. For this purporse,only small parts of the object are usually analyzed. Especially for elemental analysis, micro X-ray fluorescence is a fast and frequently used analytical method that permits sensitive and non-destructive examination.
This report describes the analysis of parts of a Roman sword. After removing the corrosion layers, the sword was analyzed with Bruker‘s μ-XRF spectrometer M4 TORNADO

The sample
The examined object is a Roman sword of a type called Gladius (see Fig. 1). It was found in the north-east of Germany,close to the town of Pasewalk. Several manufacturing features indicate that the sword was not manufactured in this region. It was most likely carried by Germanic warriors,who broke it and sacrificed it to the gods. The sword was highly corroded.

Examination of the material structure
The first examination step took place at the University of Applied Sciences HTW Berlin (Hochschule für Technik und Wirtschaft Berlin), where X-ray imaging analysis was performed on the sample. Figure 2 (left) shows a sandwich structure of carbon rich and cabon poor regions in the upper part of the sword. This is known as damascene steel, a steel type that combines hardness with elasticity.
The X-ray image of the area close to the handle shows two pieces of inlaid work, one on each side of the blade as it can be seen in figure 2 (right).
The inlaid work shows on one side Victoria, the flying goddess of victory and the tutelary goddess of the Roman emperor. On the other side of the blade is an eagle, the symbol of the Roman legion (see Fig. 3).
From this point on, the examination focused on the elemental composition of the inlaid work and the blade, as well as on the reconstruction of the shape of the inlaid work by using an elemental imaging system.

Instrumentation
The examination was performed using the μ-XRF analysis method in Bruker‘s M4 TORNADO. The following measurement conditions were used:
Measurement in air
Excitation with 50 kV, 600 μA
Distribution analysis with HyperMap in an area of approx.22 x 16 mm (450 x 330 pixel)
Acquisition time per pixel: 10 ms

·  使用XFlash®探测器高速地获取样品图谱，另外，使用多个探测器可以进一步提高测量速度。

·  基于无标样分析法准确定量分析块状样品，准确分析多层膜样品。

·  具有便捷进样功能的可抽真空的样品室

 行业应用：

1.地球科学（岩心、岩石、沉淀物、微体化石、年轮等多元素分布成像、行扫描与相序分析。）

2.司法鉴定、法医及痕量分析（对衣物上的弹孔进行射击残留物GSR分析）

3.艺术与考古(对文物进行颜料、色料的成分分析，修复文物)

4.质量控制与故障分析仪（电子和电子部件元素分析，ROHS分析）

5.发动机部件、电机/润滑油（识别电机/润滑油中的发动机磨损产物）

6.生命科学（检查树木横断面/叶子/树根年轮）

7.材料科学（钢材腐蚀检验）

8.环境科学(土壤重金属、污水污泥重金属分析、空气和城市废物)

9.过滤器上的薄膜（空气滤膜）
