Using In Situ IR Spectroscopy Measurements of Vermiculite Insulation to Determine Its Origin

The goal of this study was to determine if in situ near-infrared reflectance measurements, using portable spectrometers, could be used to reliably identify the source of vermiculite ore and therefore its potential to contain asbestos. The method developed can be used to determine vermiculite insulation's source and estimate its potential amphibole content, providing low-cost analysis...
