Title: Background Gas Effects on Infra-Red Analysis of Carbon Dioxide.
Author: Corcoran Jr, PJ; Lanphier, EH; Blodgett Jr, JR; Smith, JC; Nevels, ZJ
Abstract: Infra-red carbon dioxide analyzers have been used in many experimental diving unit studies involving a variety of breathing media. Calibration of the instruments has routinely been conducted with mixtures of carbon dioxide in the air. It was recently discovered that this use of an air-CO2 calibration curve could introduce errors when the 'background' of samples being analyzed was a gas other than air. Investigation of the magnitude of errors introduced and of their reproducibility under various conditions was undertaken. It was found that the errors were definite but not large, that valid correction of previous data was possible under most conditions, and that relatively simple procedures would suffice to eliminate this source of error in future work.
