The FaBRECC lab is a shared facility between myself and Dr. Neal Scott. Research in the lab emphasizes the measurement of organic and inorganic constituents in aqueous samples, the analysis of nutrients (C, N, P) in soil and vegetation samples, and the measurement of key greenhouse gases.  The overall goal of much of the research is to increase our understanding of the impacts of climate and land-use change and permafrost disturbances on terrestrial and fluvial biogeochemical cycles and net greenhouse gas emissions.

Research in the lab is supported by a Millipore water system producing 18 Mohm, < 5 ppb TOC water and a Miele dishwasher system.  Other analytical equipment dedicated to low-level chemical analyses includes:

  • Shimadzu Total Organic Carbon analyzer with high sensitivity catalyst and a Total Nitrogen module
  • *New* Thermo Scientific Dionex 5000 liquid ion chromatograph equipped for the analysis of anion and cations from a single sample, and electrochemical detection for simple sugars (NSERC Research Tools and Instruments grand led by M. Lafrenière and S. Lamoureux).
  • Horiba Aqualog benchtop fluorometer for DOM, to simultaneously measure absorbance spectra and fluorescence Excitation-Emission Matrices
  • Laminar flow hood provides a clean air (Class 100) bench space for sample preparation and processing

Other equipment is dedicated to measuring higher concentrations of various anions and cations in water and salt extracts of soil samples, determination of carbon and nitrogen in soils and sediments, and measurement of greenhouse gas production from soils. These include:

  • Astoria Pacific Astoria2 automated colorimetric system equipped with an auto-diluter
  • LECO TruSpec carbon/nitrogen analyzer
  • SRI Greenhouse Gas GC system for simultanneous determination of carbon dioxide, methane, and nitrous oxide production from soils

Assorted gas pumps and flow controllers are used to prepare custom mixes of gases for analytical standards and soil incubations.  Future additions to the lab include a Shimadzu Greenhouse Gas Analyzer equipped with an autosampler.  The facility is also supported by various small pieces of laboratory equipment: pH meters, conductivity meters, pipettes, ovens, furnaces, incubators, shakers, and balances. Field research is supported by a wide range of soil and stream water sampling and monitoring equipment (see www.capebountyresearch.com)

Dr. Lamoureux’s EVEX facility also houses a Los Gatos Research water stable isotope analyser, which is an instrument obtained through an NSERC Research Tools and Instrument grant led by Dr. Kent Novakowski in Civil Engineering, with Drs. Lamoureux and Lafrenière as co-applicants.
