SYSTEM FOR AND METHOD OF COMBINED LIBS AND IR ABSORPTION SPECTROSCOPY INVESTIGATIONS

摘要

A system (102) for determining properties of a sample (114) comprises a LIBS detector (104,106) and an infra-red absorption detector (108,110) for interrogating a sample (114) to generate LIBS spectral data and infra-red absorption spectral data respectively; and a data processor (112) adapted to apply at least one chemometric prediction model, each constructed to link, preferably quantitatively link, features of both LIBS and absorption spectral data to a different specific property of the sample, to a combined dataset derived from at least portions of both the LIBS and the absorption data to generate therefrom a determination, preferably a quantitative determination, of the specific property linked by that model.
