Characteristics Sampling Efficiency and Battery Life of Smart Air Sampler System (SASS) 3000 and SASS 3100
Abstract
This test was conducted to support Joint Project Manager Guardian Product Manager Consequence Management decision making for modernizing National Guard Civil Support Team equipment sets. The sampling efficiency of the newer Smart Air Sampler System (SASS) 3100 filter based aerosol sampler was compared to the earlier SASS 3000 filter based aerosol sampler. Both SASS units were manufactured by Research International (Monroe, Washington). The SASS 3100 was modified from the SASS 3000 to incorporate operational suitability lessons learned from the Expeditionary Biological Detection Advanced Technology Demonstration. The battery life of the units was also determined in this study. The sampling efficiency was determined using inert and bio-particles. Solid Polystyrene Latex microspheres of 3.1 microns and fluorescent oleic acid particles of 3.7 microns were used as the inert particle challenge aerosol, and 3.5 microns of Bacillus atrophaeus (formally known as Bacillus globigii [Bg]) was used as the bio-particle. The sampling efficiency test results show no statistically significant difference in sampling efficiency between the units. The battery life test results showed that the non-rechargeable lithium MnO2 BA 5390/U battery that was used with the SASS 3100 provided a longer run time of more than 28 hr compared to the SASS 3000 run time of 9.5 hr with the commercial off-the-shelf internal rechargeable 5 A.hr lithium-ion battery.
