High-Volume Aerosol Concentrator

SASS 4000 high-volume aerosol concentrator

The SASS® 4000 is a highly efficient, high-volume aerosol concentration device. Many applications require the collection and analysis of aerosol particles, ranging from environmental air sampling, counter-terrorism to epidemiology, medicine, and agriculture. These applications typically involve the monitoring or collection of airborne plant, animal or human pathogens.

The SASS 4000 Aerosol Concentrator overcomes three problems often encountered in aerosol sample analysis:

  • The targeted pathogen may be present at a very low concentration
  • The collection process involves too small an air sample to be statistically valid
  • Available bioassay methods are not sensitive enough

At 4,000 LPM, the concentrating power of the SASS 4000 compensates for all these problems.

The SASS 4000 can be connected to a wet-air sampler for collection of particulates into a liquid form. CBRN International's SASS 2300 wetted-wall air sampler is an ideal instrument for this purpose.

Primary airflow: 4,000 liters/min is sampled uniformly from around the pre-concentrator’s circumference.
Secondary airflow: 30–360 LPM at +0.4 cm of water static head maximum; aerosol concentrate typically delivered to a wet or dry sampler such as the SASS 2300 or SASS 3100, respectively.
Aerosol range: Aerosols greater than 0.5 microns in diameter with a particle density of 1.0 g/cc.
Secondary airflow connection: Hose barb fitting on base surface for nominal 3.8 cm ID hose.
Concentration enhancement: 4–15 times typical for aerosols greater than 0.5 microns in size. Performance also influenced by secondary airflow- request specific data for your application.
