AI Technical Summary
Existing portable chemical reagent rapid samplers suffer sample loss due to reagent backflow caused by changes in external environmental pressure during stormy weather or when near large ventilation equipment.
The sealing system, driven by an electric actuator, draws out the reagent by generating negative pressure and uses a strong spring and sealing plate to prevent backflow. At the same time, sealing rings are used at the pipe joints to ensure a tight seal and prevent leakage.
The sampler's stability and anti-reflux capability have been improved in complex environments, ensuring sample integrity and reducing reagent loss during transport.
