APPARATUS FOR SAMPLING AND ANALYZING GREENHOUSE GAS OF ARABLE LAND

摘要

PURPOSE: An apparatus for collecting and analyzing greenhouse gas is provided to simultaneously collect greenhouse gas from a plurality of chambers in which crops are grown, and to accurately analyze the greenhouse gas without an error. CONSTITUTION: An apparatus for collecting and analyzing greenhouse gas comprises a plurality of chambers(100), a plurality of flow channel changing valves(200), a manifold(240), a gas injection unit(250), a plurality of sample loops, an air pump(400), and an analyzer(500). The gas injection unit is connected to the manifold and injects gas into the manifold. The sample loop is connected to a third port(230) of the flow channel changing valve at one side. The air pump is connected to the other side of each sample loop and guides greenhouse gas into the sample loop. The analyzer analyzes the guided greenhouse gas.
