Area Source Sampling Protocol using the ODOFLUX™ Sampling Chamber
A surface source is defined as a source of diffuse emissions over a certain area. Landfills, contaminated sites, compost and manure, waste water treatment pools, spreading fields and others are examples of such sources.
Gas or odor sampling from surface sources is carried out using TEDLAR© or NALOPHANE© bags or chemically inert containers. All piping, surfaces and connections in contact with sampled gas are TEFLON©, NALOPHANE©, TEDLAR©, stainless steel, glass or acrylic resin.
The flux chamber consists of a cylindrical enclosure with a spherical top. The flux chamber is supplied with a controlled flow of ultra pure air from a cylinder. The pure air can also be generated in the field by a filtration system and a compressor. The bag introduced in the lung chamber is connected by a TEFLON© tube to the outlet of the flux chamber. The air is aspirated from the lung chamber using a pump at a controlled flow rate. Due to negative relative pressure, the bag is then filled with gas from the flux chamber.
ODOFLUX allows precise flux measurement in g/m³s or in o.u./m³s.
