Gas trap for environmental monitoring and chemical element analysis

The invention relates to the technical field of environmental monitoring equipment, and discloses a gas trap for environmental monitoring and chemical element analysis, the gas trap comprises a base, the center of the upper surface of the base is fixedly connected with a fixed cylinder, an adjusting rod is inserted in the fixed cylinder, the top of the adjusting rod is fixedly connected with a connecting seat, and the connecting seat is fixedly connected with a gas inlet pipe. A groove is formed in the upper surface of the connecting base, and the inner side wall of the groove is rotationally connected with a transverse rod through a damping rotating shaft. According to the gas trap for environmental monitoring and chemical element analysis, through cooperative arrangement of the collecting box, the collecting hole, the collecting hopper, the collecting pipe, the connecting pipe, the collecting main pipe, the negative pressure pump, the output pipe and the collecting bottle, gas at a monitoring point is trapp
