Description

Product Details Models 128, 129, 130 and 131 are High Flow Impactors (HFI) ideal for sampling particles at low concentrations (pristine environments), for collecting more mass per stage as compared with conventional MOUDI impactors, or for obtaining samples in shorter sampling intervals. 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.
