Abstract:
A gas chromatograph is provided with a separation column, a column oven, a sample vaporization unit, a carrier gas supply unit configured to supply a carrier gas to the sample vaporization unit, a detector, a carrier gas flow rate control unit configured to control a flow rate of a carrier gas to be supplied from the carrier gas supply unit to the sample vaporization unit so that a column linear velocity becomes constant, a detector gas supply unit configured to supply a detector gas, and a detector gas flow rate control unit configured to control the flow rate of the detector gas so that a total flow rate of the carrier gas to be introduced into the detector and the same type of a detector gas as the carrier gas becomes a preset constant flow rate.

Claim (Index 1):
A gas chromatograph comprising:\n a separation column configured to separate a sample for each component; a column oven configured to accommodate the separation column and control a temperature of the separation column; a sample vaporization unit connected to one end side of the separation column and configured to vaporize an injected sample; a carrier gas supply unit configured to supply a carrier gas for introducing a sample gas vaporized at the sample vaporization unit to the separation column to the sample vaporization unit; a detector connected to the other end side of the separation column and configured to detect a sample component separated in the separation column; a carrier gas flow rate control unit configured to control a flow rate of the carrier gas to be supplied from the carrier gas supply unit to the sample vaporization unit so that a column linear velocity becomes constant; a detector gas supply unit configured to supply at least one type of a detector gas including a same type of a gas as the carrier gas to the detector; and a detector gas flow rate control unit configured to control the flow rate of the detector gas to be supplied to the detector from the detector gas supply unit so that a total flow rate of the carrier gas to be introduced into the detector and a same type of a detector gas as the carrier gas becomes a preset constant flow rate.
