Abstract:
Passive diffusion badges are being tested as a long-term, low-level method of analyte-specific air analysis onboard U.S. Navy (USN) nuclear submarines. Passive badge monitors for monoethanolamine (MEA) detection were tested. Long-term sampling efficiency was evaluated for a 28-day period by comparing the response of the passive badge to an active tube sampling method. Simultaneous exposure of badges and tubes at concentration levels 100% and 20% of the USN 90-day submarine-specific limits was performed. High-level and low-level concentrations were tested to examine the response range of the badge. Badge results were stable and reproducible at 100% of the USN 90-day limit (0.50 ppm) and were on average 25% lower than active sampling tube results. At the 20% level (0.10 ppm), the badge results were typically 14% lower than the tube results.
