2021.01.14 13:48, the analysis technology department Guangyu in the WS05 5422 room review atomic absorption spectrometer (measurement number: A-CA-ZKZX-2008) annual verification data found that the flame method detection limit is 0.051ug/ml, not Meet the acceptance criteria (≤0.02ug/ml). <br><br><br>The root cause of this deviation is that the SOP document does not provide enough details on the cleaning of the equipment. The inspector Chen Demin did not pay attention to the need to clean the atomizer and combustion head before the inspection. It is caused by insufficient details of the document and personnel negligence.

At 13:48 on January 14, 2021, Duan Guangyu from the analysis technology department checked the annual calibration data of atomic absorption spectrometer (measurement No.: a-ca-zkzx-2008) in room ws055422 and found that the detection limit of flame method was 0.051 UG / ml, which did not meet the acceptance standard (≤ 0.02 UG / ml).<br>The root cause of this deviation is that the SOP document does not specify the cleaning of the equipment in detail, and the calibrator Chen Demin did not pay attention to the need to clean the atomizer and combustion head before calibration. It is caused by the lack of detailed documents and personnel negligence.<br>

At 13: 48 on January 14, 2021, Duan Guangyu, Department of Analysis Technology, rechecked the annual calibration data of atomic absorption spectrometer (MetrologyNo.: A-CA-ZKZX-2008) in room WS05 5422, and found that the detection limit of flame method was 0.051ug/ml, which did not meet the acceptance standard (≤0.02ug/ml).The root cause of this deviation is that the SOP document is not detailed enough in terms of equipment cleaning, and the verifier Chen Demin did not pay attention to the need to clean the atomizer and combustion head before calibration. It is caused by insufficient details of documents and negligence of personnel.
