Portable Raman Spectroscopy for Art & Archaeology Applications
Technické články | 2020 | MetrohmInstrumentace
Portable Raman spectroscopy offers non-invasive, in situ chemical analysis of paintings, ceramics, statues and other artifacts, supporting conservation, authenticity verification and monitoring of degradation.
This application overview highlights the capabilities of a portable Raman system for art and archaeology, describing field measurement workflows, key performance features and the role of spectral libraries and software for rapid pigment and material identification.
Measurements rely on a fiber-optic Raman probe for non-contact analysis, with adjustable laser power and multiple excitation options. The portable setup includes:
The system delivers adjustable laser power down to 1%, allowing safe examination of sensitive surfaces. Its lightweight, rugged design facilitates deployment in caves, ceilings and confined archaeological sites. Proven performance in published studies demonstrates reliable pigment discrimination, detection of organics and inorganics, and assessment of corrosion and oxidation effects.
Key benefits include non-destructivity, minimal sample preparation, rapid on-site results and guidance for restoration strategies. In archaeology, the method supports artifact provenance studies and environmental impact assessments without compromising artifact integrity.
Future developments may integrate hyperspectral imaging, AI-assisted spectral interpretation, expanded material databases, enhanced battery life and wireless connectivity. Coupling Raman with complementary techniques (e.g. XRF, LIBS) will further enrich analytical insights for heritage science.
Portable Raman spectroscopy, exemplified by the i-Raman series, provides a versatile, high-performance tool for nondestructive analysis in art and archaeology, underpinning conservation decisions and authenticity assessments.
