Generic air sampler probe tests

PDF Version Also Available for Download.

Description

Tests were conducted to determine the best nozzle and probe designs for new air sampling systems to be installed in the ventilation systems of some of the waste tanks at the Hanford Site in Richland, Washington. Isokinetic nozzle probes and shrouded probes were tested. The test aerosol was sodium-fluorescein-tagged oleic acid. The test parameters involved particle sizes from 1 to 15 {mu}m, air velocities from 3 to 15 m/s. The results of the tests show that shrouded probes can deliver samples with significantly less particle-size bias then the isokinetic nozzle probes tested. Tests were also conducted on two sample flow ... continued below

The results of the tests show that shrouded probes can deliver samples with significantly less particle-size bias then the isokinetic nozzle probes tested. Tests were also conducted on two sample flow splitters to determine particle loss as a function of aerodynamic particle size. The particle size range covered in these tests was 5 to 15 {mu}m. The results showed little particle loss, but did show a bias in particle concentration between the two outlets of each splitter for the larger particle sizes.
