HFI High Flow Impactor 131B

Product Details

This HFI MOUDI™ impactor is available with 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.

Applications

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

Features and 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
• 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
