An apparatus for presenting a sample of material for analysis by a laser-based analyser comprises a chamber, a first window for admitting laser radiation to the chamber, sample presentation means 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.
