Prompt Gamma-Neutron Activation Analysis (PGNAA) Material Analyzers for Coal and Cement Industry

Prompt-gamma neutron activation analysis (PGNAA) is a technique used for determining the presence and amount of many elements simultaneously in samples ranging in size from small to very large. It is a non-destructive method, which provides real-time analysis through continuous measurement of the elemental composition of the material under test.

The sample is continuously irradiated with a beam of neutrons from a californium-252 source. The elements of the sample absorb these neutrons and emit prompt gamma rays which are captured by a sodium iodized crystal and measured with a spectrometer. Each element emits a unique gamma ray. The energies of these gamma rays identify the neutron-capturing elements and the intensities of the peaks at these energies reveal their concentrations. Customers use this information to analyze the composition and the quantities of elements such as sulfur, silicon, calcium, oxides, carbon, etc. which then is used to determine total moisture and more accurate BTU.

PGNAA applications include the analyzation of coal, cement, and other minerals.
