本次偏差为实验员没有仔细查看SOP，对SOP内容理解错误，导致限度溶液

This deviation is that the experimenter did not carefully check the SOP, and misunderstood the contents of the SOP, which resulted in the inconsistency of the preparation of the limit solution and the SOP: the limit solution should have been diluted from 100% control stock solution, and the actual use of the 100% control solution diluted The configuration error, and the second person's review did not find it, is a personnel error.

This deviation is that the experimenter did not carefully look at sOP, the SOP content understanding error, resulting in the limit solution formulation and SOP inconsistent: the limit solution should have been diluted by 100% control reserve solution, and the actual use of 100% control solution diluted, limited solution preparation error, and the second person review also did not find that it belongs to the personnel error.

The deviation is that the experimenter did not carefully check the SOP and misunderstood the content of SOP, resulting in the inconsistency between the preparation of limit solution and SOP: the limit solution should have been diluted by 100% control stock solution, but it was actually diluted by 100% control solution, the preparation of limit solution was wrong, and the second person did not find it, which was a personnel error.<br>
