摘　　要：基于阀柱切换的多维气相色谱技术在炼厂气分析中的应用十分广泛,概括介绍了针对不同气体类型开发的三阀四柱双通道分析系统、四阀五柱三通道分析系统、四阀六柱三通道分析系统、四阀五柱双通道分析系统、五阀七柱三通道分析系统等,对比分析了每种系统的特性,从而对炼厂气或其他工业气体的色谱分析形成系统认识。Multi-dimensional gas chromatograph with valve column switching techniques has been widely applied in the refinery gas analysis. According to the type of samples, refinery gas analyzer were divided into the following categories, three-valve-four-column system with two detectors, four- valve-five-column system with two detectors, four-valve-six-column system with three detectors, four-valve-five-column system with two detectors and five-valve-seven column system with three de- tectors. Features of each analyzer system were compared and analyzed, which would be beneficial to know about the chromatographic analysis of refinery gas and other industrial gas.
