Systems and Methods for an air slide analyzer for measuring the elemental content of aerated material traveling by air slide. The air slide analyzer has an analyzer having an entrance opening and an exit opening, and an interior tunnel adapted for aerated material conveyed by an air slide; a radiation detector proximal to the analyzer; a neutron source emitting neutrons into material within the analyzer; and a processor to analyze detected information from the radiation detector, wherein emissions from the material being irradiated with neutrons are detected by the radiation detector and analyzed by the processor to provide elemental information of the material in the analyzer.
