Abstract
Disclosed is a sampling device and method for detecting liquid. The device includes a sampling probe; an action module for actuating the sampling probe; a control module for controlling the action module; a detection module for detecting a change of a relevant physical quantity of the sampling probe and converting the physical quantity into a corresponding electric signal output to the control module. The control module processes the electric signal output by the detection module and controls the action module to actuate the sampling probe based on the electric signal. The device is capable of determining abnormal liquid suction situations, making the sampling more reliable.
