Abstract
Method of quantitatively detecting material in a sample, whereby the material is in the form of submicrometric particles covered by a photoemitting substance, and a device for practicing the method. The material in the sample is heated to a photoemitting state and subjected while in that state to photoemission measurement. The proportion of material in the sample is determined from the signal obtained from that measurement by comparison with empirical data obtained from a reference sample containing a previously detected quantity of the material or by comparison with data obtained for the material by calibration.
