Crystalline Dust Sampling using Parallel Particle Impactors

Crystalline Dust Sampling using Parallel Particle Impactors

These Parallel Particle Impactors are used for respirable crystalline silica and dust sampling.

  • They contain preweighed PVC filters allowing the customer to request respirable dust.
  • They are disposible.   So no cleaning required.  (The original PPIs were designed to be reusable, but customers preferred disposable.)
  • OSHA lists them in their final rule for silica.
  • These impactors are designed for a a flow rate of 2.0 L/min.  Different flow rates are possible with different impactors, but Assay Technology does not stock them.
  • No cyclone required.

The dust analysis will be performed at AT Labs, however the silica analysis will be performed by a subcontracted laboratory.
