AOAC SPADA February 2015 Meeting Book

2/3/2015

Bio CAPAT Overview • Point Detectors ‐ Sample Aerosol Directly ‐ Reliability Time to Detect Distinguish from Background ,  ,  ‐ Particle Size: Threat Based (1 ‐ 10 micron) • Identifiers ‐qPCR, ELISA, UV Emission, AA • Standoff Detectors (AOF not funded) ‐ Back Scatter + Emission: Good Sizing, Concentration  ‐ Poor ID • Decon and Equipment Survivability ‐ Particulate in nature (surface) , deactivation, filtration   efficacy.  Nuclear decon often related

A Few Biological TECNs 

• Standardized Interferent Recipes. • Standard Unit of Measure for Bio Detection     ACPLA TALA p BUALA ,  . Infectivity, Virulance and Viablity Based More Short Term • Background vs Challenge: UV Vis Particle Sizer. • Threat realistic Aerosolizer for chamber tests. Crude method (threat based), Wide PSD Flux must be suitable for the low levels    associated with chamber work Current Sonotek method is very refined
