摘要：In a gas chromatography apparatus (200), a carrier gas is flowed from a carriergas supply (204) toward an analytical column (212) at a carrier gas pressure. A sample isadded to the carrier gas to form a sample gas. The sample gas is flowed through the

analytical column (212) to a gas detector (224) that includes a sample gas outlet (276)communicating with a gas buffer vessel (240). The carrier gas pressure is controlledrelative to a buffer pressure of the gas buffer vessel (240).
