Abstract

PURPOSE:To maintain the composition and concentration of gas for a long time and to obtain the accurate results of analysis, by connecting a sample introducing line with a sample discharging line communicatingly to each other and sealing tightly each sampling part independently. CONSTITUTION:A six-way cock, an eight-way cock or a three-way solenoid valve are used for a key valve apparatus 12. A sample introducing line 1 is connected to a sample discharging line 14 communicatingly to each other at a connection D of the apparatus 12. Moreover, a line part 18 having a calibration pipe 17 is provided to a branch valve 15A and the one hand of the line 18 is connected to sample lines 16 and 162 and on the other hand, the line 18 is connected to a carrier gas line 19 and a column line 20 communicatingly to each other selectively. By such constitution, the calibration pipes storing each sample are closely sealed indepently and are maintained for a long time without varying the concentration and composition of gas, thus, the accurate analysis value can be obtained.
