A control method for an automatic analyzer that can improve robustness, throughput, and measurement accuracy. The automatic analyzer includes a sample loop connected between two sample ports of a plurality of sample ports of a switch valve. The method includes the steps of: adjusting a drive parameter of the syringe corresponding to a viscosity of the sample acquired in advance; switching the switch valve to a first state in which the sipper and the syringe contact with each other without through the sample loop; driving the syringe based on the drive parameter to draw and introduce the sample through the sipper; switching the switch valve to a second state in which the syringe and the sample loop conduct with each other; and driving the syringe based on the drive parameter to introduce the sample into the sample loop.

This application discloses an auxiliary device and method for water sample purification. The auxiliary device includes a fixed support, which has an upper functional section, a middle functional section, and a lower functional section arranged vertically. The upper functional section includes a mechanical gripper that generates thrust on a syringe and a conveyor belt for transporting the syringe. The mechanical gripper drives the internal push rod of the syringe through a pressure pump. The middle functional section includes at least one adjustable support platform with a syringe fixing mechanism for docking the syringe with the purification column. The lower functional section includes a waste liquid cup and a receiving container for receiving purified water samples. The device adopts a four-section functional structure design with the fixed support as the main body. It is compact, moderately sized, and meets the portability requirements for experimental operations in various scenarios.

This invention relates to the field of transformer oil moisture content detection, and in particular to an automatic sampling method and apparatus for detecting transformer oil moisture. The method includes: setting a preset displacement trajectory for the syringe plunger; controlling a drive mechanism to drive the syringe plunger along the preset displacement trajectory, and acquiring the current position and thrust torque of the plunger in real time; determining the displacement deviation between the current position and the theoretical position, and dynamically adjusting the torque threshold; initiating torque compensation when the thrust torque exceeds the torque threshold; and pre-compensating the control command based on the torque change rate and displacement deviation. By setting the preset displacement trajectory of the plunger and acquiring the current position and thrust torque of the plunger in real time, the torque threshold is dynamically adjusted. When the thrust torque exceeds the limit, torque compensation is initiated. Simultaneously, the control command is pre-compensated based on the torque change rate and displacement deviation, overcoming problems such as insufficient thrust, missed steps, and poor repeatability caused by sudden changes in resistance or local blockage during micro-sample injection.
