ABSTRACT:
A system for detecting live insects in a commodity sample features forming a closed-loop between a stored quantity of fluid and a sample cell and a reference cell. The closed-loop and the stored fluid ensure a controlled environment during incubation and analysis of the commodity sample. This controlled environment achieves a greater sensitivity and reproducibility than prior systems.
