Abstract
The present invention discloses a method and apparatus of elemental analysis which finds particular application in the on-line analyses of the specific energy (calorific value) of coal or coke by the determination of carbon content. Analysis is achieved by a comparison of the output of neutron inelastic scatter which produces first .gamma. rays and of scatter of second .gamma. rays. Preferably 4.43 MeV carbon .gamma. rays are used and, in addition, one or more of moisture, ash, or hydrogen content of coal or coke can be measured using 2.2 MeV hydrogen capture .gamma. rays. The method and apparatus have the advantage of providing a compensated count rate that is essentially independent of sample compaction.
