Abstract
A concentrator, wherein the concentrator comprises an air processor that includes a sampled airflow inlet slot that receives a sampled airflow that contains particles containing target material. A secondary airflow inlet slot that is located downstream from the sampled airflow inlet slot. The sampled airflow inlet slot uses centrifugal force to concentrate particles containing target material into a central portion of the sampled airflow, and produces a non-collimated sampled airflow. The secondary airflow inlet slot is operable to divide a secondary airflow from at least a part of the central portion of the sampled airflow that is received by the secondary airflow inlet slot from the sampled airflow inlet slot, and is operable to divide side primary airflows from the non-collimated sampled airflow produced by the sampled airflow inlet slot. Finally, the secondary airflow flows through the secondary airflow inlet slot.
