Explore how PGNAA and PFTNA work and the key features of hardware and software that support its industrial use


Welcome to our Learning Center for PGNAA, an analytical technique used by the processing industries, notably the coal, cement, minerals processing and steel sectors, for non-contact, non-destructive online measurement of the elemental composition of bulk raw materials. 


PGNAA is the acronym for Prompt Gamma Neutron Activation Analysis. It’s a technique that requires a supply of neutrons which can come from either a radioactive source, typically Cf-252, or a neutron generator via Pulsed Fast Thermo Neutron Activation (PFTNA). We pioneered PGNAA and are highly experienced in its  successful application in demanding commodity industries.


Here’s where we share our expertise and knowledge. Find the valuable information you need to accelerate and optimize the application of both PGNAA and PFTNA by browsing through the educational assets below.
