封闭室系统通常用于测定农业土壤中的气态碳和氮排放。在实验室条件下，研究了8个试管表面对NH3、N2O、CO2和ch4两种标准气体浓度的影响。试管表面材料对气体附着力或回收率的影响是不同的，这是气体类型和浓度的函数。考虑到密闭室系统对气体测量结果的强烈影响，在选择试管表面材料时需要考虑被测气体的类型和浓度。
Closed‐chamber systems are commonly used to determine gaseous C and N emissions from agricultural soils. We investigated the effects of eight cuvette surfaces on two standard gas concentrations of NH3, N2O, CO2, and CH4under laboratory conditions. Cuvette surface materials differentially affected gas adhesion or recovery as a function of the type and the concentration of the gases. Given the strong effects on results of gas measurements in closed‐chamber systems, both the type and the concentration of the measured gases need to be considered in selecting cuvette surface materials.
