If these components are not removed or treated, they may interfere with the test results of the analytical instrument or even damage the equipment. Therefore, reasonable and effective pretreatment steps are essential to obtain accurate and stable test results.

[0003] Currently, sample loading is a time-consuming and error-prone step in water sample pretreatment experiments. The loading method usually requires manual operation, and manual loading requires operation of each sample one by one, which is time-consuming, limits the high-throughput processing capability of the experiment, and is prone to sample overflow or residue in the loading device, resulting in sample waste and inaccurate data.
