Neutron Activation Analysis
Multi-element compositional analysis for archaeology, art authentication, and environmental tracing.
The Challenge
Non-Destructive Multi-Element Analysis at Parts-Per-Billion
Determining the precise elemental composition of materials is fundamental to archaeology, art authentication, and environmental science. Many conventional techniques require destroying the sample — unacceptable for irreplaceable artifacts, valuable artworks, or forensic evidence. Neutron Activation Analysis offers non-destructive, multi-element sensitivity down to parts-per-billion. ASPL Fusion’s knowledge graph has identified 671 NAA-related papers — the single largest application domain in neutron science literature.
Our Approach
High-Sensitivity Elemental Fingerprinting
ASPL Fusion provides NAA services by irradiating samples with neutrons and measuring characteristic gamma-ray emissions. The technique simultaneously identifies and quantifies 30+ elements in a single measurement — without destroying or even touching the sample.
Our NuKG knowledge graph contains 671 papers on archaeological NAA applications, representing the largest domain in our 24,000-paper corpus.
Why It Matters
Key Benefits
Non-Destructive
Samples are irradiated and measured without physical contact, dissolution, or damage — critical for irreplaceable artifacts and forensic evidence.
Multi-Element Sensitivity
A single measurement quantifies 30+ elements simultaneously, from percent-level constituents to parts-per-billion trace impurities.
Provenance Determination
Elemental fingerprints reveal geographic origin, manufacturing technique, and material authenticity — the gold standard for archaeological analysis.
Who This Serves
Industries & Applications
- Archaeological departments and museums determining artifact provenance and dating
- Art authentication laboratories verifying the origin and age of paintings and antiquities
- Environmental agencies mapping contamination sources through trace element analysis
