Environmental Engineering Lab Cluster

The Environmental Engineering Laboratory Cluster is located on the second floor of the Advanced Technology Research Center (ATRC) on the main Stillwater campus. This cluster consists of five adjacent rooms totaling 3,440 ft2 including an analytical laboratory, a microbial molecular analysis lab, two wet laboratories, and one microplastics laboratory (Fig.1). Office spaces for graduate students are located on the same floor. The ATRC is managed by full time staff in the College of Engineering, Architecture, and Technology.

In Spring 2021, the Environmental Engineering Laboratory Cluster housed approximately 20 PhD, MS, and undergraduate researchers. Environmental Engineering research at OSU has seen a growth of 68%, 37%, and 22% in year-over-year expenditures over the last three years, and currently has over $300K of research expenditures per year.

  • Major Equipment Located in the Environmental Engineering Laboratory Cluster

    Major equipment of the analytical lab includes three Agilent gas chromatographs (GC): GC 7890 with-flame ionization detection (FID) with a liquid autosampler (Fig. 2A), GC 6890 with electron capture detection (ECD) and thermal conductivity detection (TCD) (Figure 1B), and GC-TCD 8890 with two channels with a direct gas line for continuous analyses (Fig 2C).
