Patent ID: 7006919

Claim:
An apparatus for measuring the absolute values of at least one component of a bulk material, said apparatus comprising: a first data set representing a relative component ratio of the bulk material, said relative component ratio produced by a prompt gamma neutron activation analysis (PGNAA) device; a second data set representing a relative weight/impurity ratio of the bulk material, said relative weight/impurity ratio produced by a dual-energy gamma attenuation (DGA) device; and a processor in communication with said PGNAA device and said DGA device, said processor programmed to execute a process including: receiving said relative weight/impurity ratio, receiving said relative component ratio, determining an absolute weight value from said relative weight/impurity ratio, determining an absolute impurity value from said relative weight/impurity ratio, and determining at least one absolute analyte value from said absolute impurity value and said relative component ratio.
