Butnor, J.R. | Maier, C.A. | Johnsen, K.H.
A method and apparatus are provided for measuring the gas efflux from a substrate. In particular, one or more measuring chambers receive a gas enriched air from the substrate. A respiration system sends reference air having a known gas concentration to the measuring chamber. The reference air mixes with the gas enriched air to form a mixed air, which is returned to the respiration system. The respiration system then measures the gas efflux of the substrate over the given amount of time.
