Norco building

Boise State’s new Environmental Research Building, which houses Dr. Stephenson’s laboratory

A part of Boise State University’s quest to become a metropolitan research institution of distinction is its recent construction (2011) of a new Environmental Research Building. This 5-story, 97,000 sq. ft. facility is Boise State’s first building dedicated solely to the performance of research. Dr. Stephenson’s laboratory is housed in this building. This laboratory is equipped with a typical complement of standard laboratory equipment infrastructure and safety devices to perform general chemistry applications. Dr. Stephenson is also Director of Boise State’s School of Allied Health Science. To enhance the learning aspects of environmental and occupational monitoring, Dr. Stephenson’s laboratory is equipped with a wide variety of realtime and time-integrated instrumentation used in the performance of personal and area sampling.

Lab Resources

  • Concentration limit = 2 x 106 particles/ft3
  • Particle size range = 0.3 μm to 10 μm

 Two (2) TSI® Q-TRAK™ 8552 IAQ Monitor

  • Real-time, data logging monitor having sensors that record ambient temperature, relative humidity, CO, and CO2

Four (4) Marple 290 Series Personal Cascade Impactors

  • An 8-stage impactor allowing for aerodynamic size fractionation of the an aerosol
  • Cut-points: ≥ 21.3, 14.8, 9.8, 6.0, 3.5, 1.55, 0.93, 0.52 microns and final filter

Twenty (20) Air Flow Pumps

  • Negative pressure air flow pumps having flow ranges of 5 – 5000 mL/min
  • SKC manufactured brands are available to the study

Four (4) BIOS DryCal DC-Lite Air Flow Calibrators

  • Primary calibration device for flow ranges between 5-5000 mL/min

Mettler Toledo XP6 Microbalance

The METTLER TOLEDO XP6 microbalance provides a perfect weighing performance with very fast settling times below 8 seconds. Equipped with colored touch screen display, customized screen programming, intelligent user guidance and hands-free infrared draft shield control, this microbalance is ideally suited for the exposure scientist having the need to gravimetrically analyze samples on a micro scale. Notable specifications of this instrument include a maximum capacity of 6.1 g, a readability of 0.001 mg, and a settling time of < 8 s.
