GAS SAMPLER

The invention provides a gas sampler. The gas sampler (30) is provided with a connection portion (C1) connectable to a sample tank (20), a sample loop (PL) for holding a sample gas introduced from the sample tank (20) to the connection portion (C1), pneumatic switching valves (V1 to V6) for switching a flow path connected to the sample loop (PL), a control piping (81) for transmitting a driving pressure to the switching valves (V1 to V6), a pump (31) for suctioning an inside of the sample loop (PL), and a pressure accumulation tank (80) for accumulating the pressure generated by the operation of the pump (31) as a source pressure. 提供一种气体取样器。气体取样器(30)具备：连接部(C1)，其能够与样本罐(20)连接；取样环路(PL)，其保持从样本罐(20)向连接部(C1)导入的试样气体；气动式的切换阀(V1～V6)，其对与取样环路(PL)连接的流路进行切换；控制配管(81)，其向切换阀(V1～V6)传递驱动压力；泵(31)，其用于对取样环路(PL)内进行抽吸；以及蓄压罐(80)，其将通过泵(31)的工作而产生的压力作为驱动压力的源压力进行蓄积。
