ARTIFACTS IN THE ANALYSIS AND ASSESSMENT OF LOW-COST CONTAINERS FOR SAMPLING AND STORING GREENHOUSE GASES

The objectives of this study were twofold: to assess two chromatographic methods for the analysis of greenhouse gases (GHG) and carbon monoxide, and to propose and evaluate a low-cost and reusable alternative system for their sampling and storage, using 10 different container configurations (flasks and bags). To that end, standard samples containing the gases of interest (CO2, CH4 and CO) and different types of real samples were tested. Finally, procedures for the sampling, storage and analysis of CO2 and CH4 were evaluated and optimized. Two chromatographic methods were applied, using differe...
