Abstract

A gas chromatographic system for analyzing gas components includes an analyzer, a constant temperature oven, an analyzer case, an indicator, an integrated sample conditioner, and a coupler. The analyzer includes a sample valve having a detector and a heater built therein and first and second columns wound around the periphery of the sample valve. The constant temperature oven accommodates the analyzer unit therein. The analyzer case accommodates the constant temperature oven. The indicator is protruded from the analyzer case to display analysis processes and results. The integrated sample conditioner provides an optimal condition for analysis. The coupler couples the analyzer unit with the sample conditioner so as to supply a sample gas and one of a carrier gas and a reference gas from the sample conditioner to the analyzer unit.
