Non-Viable Andersen Cascade Impactor

The Tisch Environmental ambient non-viable Andersen cascade impactor is used to sample liquid and dry airborne particulates. The TE-20-800 is a multi stage orifice  made of precision-machined aluminum stages with  successively smaller hole diameters as the particulates cascade through the device.  As a known volume of air pass through the stages, the the larger particles will “impact” on the surface of the impaction plate  and the smaller particles will remain in the air stream and cascade through each successively smaller stage until eventualy they are impacted onto an impaction plate.

Features

  • PM10 High Capacity Pre-Impactor ensures accurate separation of large particles.
  • High Sample Flow Rate of 28.3 ALPM.
  • Size seperation from >10µm to <0.4µm.
  • Optional volumetric flow controlled vacuum system.
  • Corrosion resistant alloy aluminum with silicone seals.
  • Time proven virtual elimination of particle bounce and re-entrapment.
  • Highest proven collection efficiency, reproducibility and accuracy.
  • Aerodynamic particle separation in nine size fractions.
  • 81mm sample substrates for easy handling and weighing with analytical balance.
  • Incorporates U.S. Federal standards for the “Ideal Cascade Impactor” and meets OSHA, EPA and ACGIH design requirements for respirable/non respirable fraction.
