20090113988 | Mitigation of gas memory effects in gas analysis - The gas absorption/adsorption memory effect in gas analysis can be reduced by controlling gas flow conditions such that the partial pressure of the analyte of interest is held constant, if the measured analyte concentration is within a predetermined range. Keeping the analyte partial pressure constant is helpful for mitigating the memory effect because changes in analyte absorption/adsorption rates tend to be driven by changes in analyte partial pressure. The memory effect can also be mitigated by performing concentration measurements at two or more different gas flow conditions, and employing a mathematical model to estimate true concentration and “memory effect” contributions to measured concentrations at one or more of the flow conditions. The mathematical model can be based on an assumption that the true analyte concentration is independent of flow rate or pressure, while the “memory effect” contribution to measured concentration is inversely proportional to flow rate or pressure. | 2009-05-07 |
