Abstract:

Response curves of CO₂ were determined for Beckman ir gas analyzers (models 215 and 315A) by adding small, measured amounts of CO₂ to a large volume of circulating N₂. We deduce a mathematical model for the response curves, estimate their parameters from our data, and comment on the role of this model in computer processing of masses of data resulting from such instruments. Close agreement between our experimental and theoretical results suggest that our model and approach should apply to similar instruments.
