“…9,10 Particle Induced X-ray Emission (PIXE), complemented by other (ion beam) analytical techniques is still widely used in several multidisciplinary research elds despite the advances of competitive methods like ICP-MS, XRF or synchrotron-based techniques. 11,12,13 At present, the two main application areas of PIXE in ATOMKI is the characterization of urban atmospheric aerosol pollution and archaeometry. The main advantages of PIXE are: it is fast, fully quantitative without using standards, covers a wide range of elements (Z = 6-92), usually does not require any sample preparation, very small sample mass in enough for the analysis, and non-destructive if carefully applied.…”

“…Ion beam analysis (IBA) is well-established in the field of heritage science encompassing the study of both cultural and natural heritage [15,16]. It is often described as non-invasive and non-destructive, since no sampling is needed for most of the applications, and the measured material is preserved, but this "safe" aspect has its limits.…”

Possible modifications of parchment during ion beam analysis

et al. 2022

Ion beam analysis (IBA) is an established method to determine the concentration and the distribution of elements in art and archaeological objects. However, especially for organic specimens, caution must be taken to avoid harmful effects. In this work, the possible modification of recent calf parchment samples by proton beam irradiation was investigated applying fluences (given as deposited charge per unit area) both within and beyond the usual analytical practice. Attenuated Total Reflection Fourier Transform Infra-red Spectroscopy (FTIR-ATR) and Optical Coherence Tomography (OCT) were employed to assess changes, inspected from the surface of the samples. Although both techniques are apt to detect alterations of parchment in general, in the case of particles, which deposit the majority of their energy below the surface these techniques could not detect changes at low fluences. However, a simple “bath test” (short immersion in liquid) proved that disintegration within the material had already happened. After the “bath test”, OCT and digital 3D microscopy were used to check the discontinuities in the material, especially for low fluences when the visual inspection might have missed them. Unfortunately, simply monitoring organic objects such as parchment during or after ion beam irradiation, non-destructively, is not sufficient to claim absolute harmlessness, as some studies in the past did. In line with our former findings using electron microscopy on cross sections, we found that 2.3 MeV protons with a deposited charge of 0.5 µC/cm2 caused no changes affecting the integrity of parchment but 2 µC/cm2 apparently did under the applied experimental conditions. To ensure the required analytical signal at a relatively low deposited charge, the detection system must be optimized for efficiency. Nevertheless, since the variability of the historic materials and the measurement set-ups are considerable, these values cannot be taken as absolutes, but only as guides, both for further IBA studies and for studies conducted in the past.
