摘要
The system and method for a multi-element, ultra-low SWaP chemical concentrator incorporating Applicant's own open cell foamed adsorbent material which allows high volume sampling (e.g., liters per minute) to achieve low detection limits (ppt) using high-volume, low-pressure air sources (i.e. fans or blowers) rather than pumps. The device delivers the sample directly to an analyzer without the need for a typical intermediate cryogenic trapping step. In one example, a rotary style concentrator comprises four individual foam elements. Each element can be individually heated to desorb analytes.
