Characteristics and Sampling Efficiencies of the Smart Air Sampler System (SASS) 2000Plus(Registered)
Abstract
Sampler characteristics and sampling efficiency measurements of the Smart Air Sampler System (SASS) 2000Plus(Registered) were determined at the U.S. Army Edgewood Chemical Biological Center. The sampler is a wetted-wall cyclone sampler that can be easily carried by a single person. The sampler is microcontroller-based and is designed to function as either a stand-alone unit or to be linked to other sampling, detection, or communication systems via an RS-232 data link. These tests were conducted with the unit as a manually operated stand-alone connected to an AC power source. The system continuously recycles the liquid to concentrate the sample. The designed air flow rate of the sampler is 265 L/min; however, the measured air flow rate was 307.4 L/min. (Tests conducted by the manufacturer had flow rates of 270, 320, and 540 L/min.) Sampling efficiency tests were conducted using 1 and 3 micro meter PSL microspheres, and 5, 7, 9, and 10 micro meter fluorescent oleic acid particles. The samples were analyzed by fluorometry. The results show that SASS has peak efficiencies of 65.1% +/- 3.4 for 7-micro meter particles and has a low power consumption of 14.4 W.
