Problems solved by technology

[0003] Existing samplers use a suction pump to extract the atmosphere in the filter element, and the detected object stays on the outer filter membrane. After the sampling is completed, the sampling head is removed, and the filter membrane is taken for testing. When sampling is required in different periods, then Need to disassemble the sampling head constantly to replace the filter membrane, the operation is time-consuming and laborious, and it is extremely inconvenient

Description

technical field [0001] The invention relates to a multi-membrane sampling and weighing device. Background technique [0002] In the technical field of gas sampling instruments, fully automatic samplers are widely used in the automatic sampling of air samples due to their high degree of automation and stability, providing a fast and convenient sampling device for the detection of PM10, PM2.5 and other components in the gas. The automatic sampler technology mainly uses a single-chip microcomputer to control the motor, manipulator and peristaltic pump, so as to realize the automatic membrane changing function. The pretreatment device mainly processes the gas samples for subsequent detection. [0003] Existing samplers use a suction pump to extract the atmosphere in the filter element, and the detected object stays on the outer filter membrane. After the sampling is completed, the sampling head is removed, and the filter membrane is taken for testing. When sampling is required ...
