Product Details

Models 128, 129, 130 and 131 are High Flow Impactors (HFI) ideal for sampling particles at low concentrations, for obtaining samples in short sampling intervals, or for collecting more mass per stage as compared with more conventional medium flow rate impactors. 

HFI impactors are available with 3, 4, 5 or 6 stages in the 0.25 to 10 µm aerodynamic size range. Particle deposits are collected on 75-mm substrates which can be analyzed for mass, or via chemical analysis or microscopy.

Features & Benefits: 

  • 100 L/min sampling flow rate
  • Sharp cut-off size characteristics
  • Micro-orifice nozzle plates designed for low flow resistance (under 6 kPa) and reduced particle bounce and re-entrainment
  • Up to 6 impactor stages with nominal cut points between 250 nm and 10 µm, plus a final filter (90-mm)
  • 75-mm impaction substrates designed to deposit particles in four separate quadrants for easy substrate division
  • Low inter-stage losses
  • Easily removable collection substrates allow for quick turn-around time for productive use of the instrument
  • Impactor is made of anodized aluminum for light weight, durability and nozzle dimensional stability
  • Light weight, compact design

Applications: 

  • Atmospheric aerosol sampling for size distribution and compositional analyses
  • Workplace aerosol analysis
  • Industrial hygiene studies
  • Biological aerosol characterization
