Round Chamber Construction


In use from 2008-01-01


This document outlines the construction of closed cover stainless steel chambers used within an agricultural field environment. These chambers are designed for use at the Great Lakes Bioenergy Research (GLBRC) sites in S.W. Michigan and Wisconsin. These chambers are appropriate for nitrous oxide (N2O), methane (CH4), and carbon dioxide (CO2) flux determination.


There are many reviews and publications in the scientific literature discussing similar sampling protocols and procedures for determining gas fluxes using various chamber systems, and readers are encouraged to conduct their own research on these. However, we hope this construction protocol will act as a useful guide for researchers and technicians undertaking GHG sampling in the field. Naturally, modifications and replacement of the equipment we list and other laboratory or field operations may be necessary depending upon the particular working environments encountered, and should be adopted when and where appropriate.
