1. A method, comprising: controlling a laser induced breakdown spectroscopy (LIBS) detector to generate LIBS data based on laser induced ablation of at least a portion of a sample, the LIBS data corresponding to wavelength dependent intensity variations of optical radiation having been emitted from the portion of the sample; controlling an infra-red absorption detector to generate illumination data based on illumination of at least the portion of the sample with infra-red energy, the illumination data corresponding to wavelength dependent intensity variations of illuminating infrared radiation reflected from the portion of the sample; adjusting the sample to expose a plurality of portions of the sample to laser induced ablation and infra-red illumination; constructing a combined dataset derived from at least a portion of the LIBS data and at least a portion of the illumination data; and determining at least one property of the sample based on an association between the combined dataset and the at least one property of the sample.
