Which tools should be used to record the most complete data about a gas

The tool that should be used to record the most complete data about a gas is the gas chromatograph. A gas chromatograph is an analytical instrument that measures the composition contains in a gas sample. The sample of solution is injected into the instrument and enters as a stream of gas which transports the sample into a separation tube known as the column. The detector then measures the quantity of the components that exit the column.
