Analysis of Greenhouse Gases by Gas Chromatography
Analysis of Greenhouse Gases by Gas Chromatography
INTRODUCTION
Nitrous Oxide (N 2 O), Carbon Dioxide (CO 2 and Methane (CH 4 are considered to be very powerful greenhouse gases. These gases reflect in the atmosphere, stopping the incoming and outgoing radiation that warms the Earth, thus causing the greenhouse effect Continuously measuring the greenhouse gases gives insight into the source of the emissions, helping us fight climate change A SCION 456 GC was custom configured specifically for the analysis for all three gases in a single matrix of atmospheric air containing water vapour.

CONCLUSION
A SCION 456 GC was configured as a
greenhouse gas analyser for the analysis of carbon dioxide, methane and nitrous
oxide in a single run Repeatability data was excellent showing that the system
is perfectly suites for the analysis of greenhouse gases This system is highly
flexible with the application range easily expanded to cover CFC’s and SF 6.
