Carbon Dioxide Monitoring.
Abstract
The program was initiated to establish the feasibility of applying bioluminescent technology for monitoring of carbon dioxide (CO2) in life-support systems for divers, swimmers and underwater habitats. Experiments were performed to obtain bioluminescent cultures which are sensitive to levels of carbon dioxide as low as 81 ppm, in an 80% helium and 20% oxygen (life-support) gas mixture--at hydrostatic pressures up to 1000 psig. Fourteen luminescent cultures were tested under conditions of varying pressures, gas proportions, sample sizes, and flow rates. Strong responses to low concentrations of CO2 were exhibited by five cultures--thereby demonstrating the feasibility of employing a luminescent detection system in the environments of interest.
