The demand for reliable and scientific authentication of luxury goods has rapidly increased with the expansion of the global resale market. InsightViewTech (IVT) and Bunjang has developed a patented analytical platform that combines portable X-ray fluorescence (XRF), near-infrared (NIR), and Fourier-transform infrared (FT-IR) spectroscopy to perform non-destructive authentication of high-value materials through chemometric modeling.
The XRF module quantifies the elemental composition of metallic components such as brand logos and zippers. The NIR module characterizes organic materials including leather, textiles, and synthetic composites. Complementary FT-IR spectra provide molecular-level confirmation of adhesives, coatings, and multilayer structures.
Chemometric analysis, including principal component analysis (PCA) and partial least squares discriminant analysis (PLS-DA) and soft independent modelling of class analogies (SIMCA), enables the integration of these multi-modal spectral datasets into a unified classification framework. Using IVT’s proprietary spectral database of genuine and counterfeit references, the system provides rapid, repeatable, and objective authentication in the field.
This presentation introduces the concept and experimental validation of IVT’s multi-spectroscopic platform, emphasizing how chemometrics enhances portable instrumentation for non-destructive verification. The approach demonstrates how a scientifically standardized methodology can improve trust, traceability, and material integrity in the global luxury market.
