摘要： An apparatus for presenting a sample of material for analysis by a laser-based analyzer 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.

摘要： An apparatus for analyzing material, such as coal, comprises subjecting the coal (14) to laser light The laser light is used to vaporize and ionize a small amount of the coal to produce spectral emissions. A plurality of detection, (26, 30, 34) each of which detect a part of the spectrum of the spectrum emissions, collect spectral information and pass it to data collection means (38, 40, 42). The data is then analyzed to determine the presence and/or amount of one or more elements or species in the coal. In a preferred embodiment, the apparatus, has a plurality of data collection means (26, 30, 34), with each of the plurality of detection means being associated with a respective data collection means (38, 40, 42). The apparatus provides rapid and accurate analysis of the coal. The apparatus may be used to analyze coal on conveyor belt or coal in a seam in the ground.
