APPARATUS FOR PRESENTING A SAMPLE OF MATERIAL FOR ANALYSIS

摘要

An apparatus for presenting a sample of material for analysis by a laser-based analyser comprises a chamber (52), a first window (72) for admitting laser radiation to the chamber (52), sample presentation means (64) for presenting a sample such that said laser radiation can impinge upon the sample, and a plurality of second windows (76, 78, 80, 82) for receiving radiation emitted from the sample, said plurality of second windows (76, 78, 80, 82) adapted to pass radiation emitted from the sample to a plurality of detector means. The apparatus further includes a gas inlet (98) and a gas outlet (100) to enable the atmosphere inside the chamber (52) to be controlled.
