Multi-point VOCs online continuous sampling and monitoring device and method

The invention discloses a multi-point VOCs online continuous sampling and monitoring device and method. The multi-point VOCs online continuous sampling and monitoring device comprises: an analytical instrument, an air exhaust mechanism, an air storage mechanism, a plurality of sampling pipes, a communicating piece, a first control valve and a second control valve; each sampling pipe is communicated with the communicating piece through the first control valve, the communicating piece is communicated with the gas storage mechanism, and the gas storage mechanism is communicated with the analytical instrument and the gas pumping mechanism through the second control valve. The multi-point VOCs online continuous sampling monitoring device can perform continuous online sampling on VOCs at different positions in a long distance in a short time, and performs quantitative detection on unknown VOCs in the environment through an analytical instrument. 本发明公开了一种多点位VOCs在线连续采样监测装置及方法。该多点位VOCs在线连续采样监测装置包括分析仪器、抽气机构、储气机构、采样管、连通
