High efficiency aerosol sampling stations ASS-500 and HVS-30

Technical data:

Aerosol Sampling Station, prod. CLOR Warszawa

  1. 1990 - II prototype, deeply modified in 2001
  2. 1995 - standard production model, modified in 1999
Engine WPMA-125F (flow: 500 - 800 m3/h)
infrared heater, flow rate meter "VORTEX"
scintillation spectrometer AS-01 connected to PMS station computer,(only in station from 1995/9)

High Volume Sampler, prod. Atmoservice, Poznań, 2002

Stabilized flow: 30 m3/h, two heads (PM-2,5 lub PM-10)

Application:

Permanent collection of atmospheric aerosols from ground level air using Petryanov FPP-15-1.5 filters. Filters are changed weekly. Low background gamma spectrometric measurements are used to determine qualitatively isotopic composition of dust and to measure its activities. ASS-500 belongs to whole country Network for Early Warning on Nuclear Accidents organized by CLRP and National Atomic Agency (PAA). Modified in 2001 in IFJ second prototype of ASS-500 allows for simultaneous collection of aerosols and gaseous fractions of iodine on additional charcoal filter.
