Analysis System for Measurement of CO2 Mixing Ratios in Flask Air Samples
TL;DR: In this paper, a system for measuring the concentration of CO2 in flask air samples from the NOAA/CMDL worldwide flask sampling network is described up to 180 samples per day can he analyzed using a nondispersive infrared CO2 analyzer All data acquisition and instrument control operations are handled by a Hewlett-Packard Series 300 desktop computer.
