Solid or liquid samples of one @G02680@ or more are generally used in @X06718@. If the sample is thick enough so that the intensity of characteristic fluorescent radiation is not significantly modified by an increase in thickness, the sample is described as a @B00756@ of effectively infinite thickness.
