Original Abstract

Fast LIBS chemical mapping of uranium ores enables obtaining complex information for a relatively large area in a short time at resolution adjusted by raster step. The scope of advantages of LIBS in comparison to other methods routinely used for ore mineralization studies comprises mainly the relatively simple and robust equipment, possibility to detect a broad spectrum of elements and minimal requirements for the sample preparation [1]. Moreover, multivariate analysis was found viable for large datasets of raw spectral information and brought new insight into high dimensional mapping [2]. The aim of this study is the investigation of uranium ore sample using combination of LIBS and LAICP- MS chemical mapping. Experimental system for fast LIBS chemical mapping consists of Nd:YAG laser (Q-Smart, Quantel) with fundamental wavelength 1064 nm, repetition rate 20 Hz and pulse duration 5 ns. Laser pulse was introduced on the sample surface by a series of mirrors and then focused by a 30 mm focal length glass doublet (Thorlabs, USA). Collection optics focused the plasma radiation into a bundle of four fibers that transport radiation to a four-channel spectrometer (Avantes, Netherlands). The mapped area was 4.0 × 23.2 mm, which resulted in a chemical map of 51 × 290 locations (with crater distance 80 μm).
