Particle Calibration Laboratory

The particle calibration laboratory at the University of Minnesota was established by Dr. Bernard Olson at the University of Minnesota Department of Mechanical Engineering in 1999. The laboratory has extensive experience working with the following industries and agencies:

  • Bioaerosols (Porcine Reproductive and Respiratory Syndrome, Influenza A, and Bacteriophages; In collaboration with Professor Montserrat Torremorell, University of Minnesota College of Veterinary Medicine)
  • Pharmaceutical Industry
  • Kitchen Ventilation
  • Mining Industry
  • Filtration Industry
  • Environmental Protection Agency
  • Lawrence Berkeley National Laboratory
  • Sandia National Laboratory
  • Southwest Research Institute
  • Argonne National Laboratory

The laboratory is equipped Particle Size generation and measurement instrumentation in the 3 nm – 20 micrometer size range and is able to perform a wide variety of standard certification, collection efficiency, control technology pressure drop, flow rate measurements, as well as bioaerosol testing (with limited virus testing in-house, and expanded tests possible via collaboration with the College of Veterinary Medicine). The laboratory follows Good Laboratory Practices (GLPs) and is able to design custom test apparati and methods to fit customer needs. The Particle Calibration Laboratory is additionally able to carry out ASHRAE 52.2 particle filtration efficiency and loading tests and ASHRAE 146.2-2016 gas testing.

For questions on laboratory calibration or to request a quote for particle calibration work, please contact Dr. Bernard Olson or Professor Chris Hogan. Laboratory experiences are carried by a combination of PhD staff (full time and researchers and post-doctoral associates), PhD students, and Mechanical & Aerospace Engineering undergrad students at the University of Minnesota.
