DEFINITION

Classification: 378/49

With spatially dispersive energy analysis:

(under subclass 45) Subject matter including specially separating fluorescent X-rays of different frequencies prior to determination of the intensity thereof.

(1) Note. This subclass requires that the origin of the X-rays being analyzed is an analyte which is excited to fluorescence by primary X-rays, while the means for spatial energy dispersion of X-rays of subclass 82 will function regardless of the manner of production of the X-rays.
